Summary:
This adds support for bundling custom widgets with the Grist app, as follows:
* Adds a new `widgets` component to plugins mechanism.
* When a set of widgets is provided in a plugin, the html/js/css assets for those widgets are served on the existing untrusted user content port.
* Any bundled `grist-plugin-api.js` will be served with the Grist app's own version of that file. It is important that bundled widgets not refer to https://docs.getgrist.com for the plugin js, since they must be capable of working offline.
* The logic for configuring that port is updated a bit.
* I removed the CustomAttachedView class in favor of applying settings of bundled custom widgets more directly, without modification on view.
Any Grist installation via docker will need an extra step now, since there is an extra port that needs exposing for full functionality. I did add a `GRIST_TRUST_PLUGINS` option for anyone who really doesn't want to do this, and would prefer to trust the plugins and have them served on the same port.
Actually making use of bundling will be another step. It'll be important to mesh it with our SaaS's use of APP_STATIC_URL for serving most static assets.

Allows bidirectional / cyclic linking for same-record cursor links.
This should allow multiple sections to all synchronize their cursors,
such that clicking in any one of them will move all the others.
Works even if some sections in the cycle have rows filtered out (the
filtered-out sections might desync their cursors, but the correct cursor
position will still propagate downstream, and they'll re-sync if clicking on
a row that is present in them)
Under the hood, each cursor has a _lastEditedAt counter, updated when
a user's action changes the cursor in a section, such that we can always
tell which section was touched most recently. This is used to resolve
conflicts stably when dealing with cycles or chains of cursor-links.
Updated selectBy and recursiveMoveToCursorPos to handle cycles
Updated tests for selectBy behavior
However, main bidirectional-linking tests are not in this commit, they'll come in a subsequent PR
* Linkingstate Refactor, and displaying link info in rightpanel

Bugfix: Disables linking from Attachment columns
Bugfix/Behavior change: changed linking with empty RefLists to better
match behavior of refs.
for context: Linking by a blank Ref filters to show records with a
blank value for that Ref. Previously this didn't work with RefLists.
Linking from a blank refList would show no records
(except in some cases involving summary tables)
Fixed this so that linking by a blank val consistently means "show
all records where the corresponding col is blank"

Fixes a problem reported here: https://community.getgrist.com/t/exporting-the-records-in-a-linked-view/2556/4
The download CSV/Excel link now contains an additional `linkingFilter` URL parameter containing JSON-encoded `filters` and `operations`. This object is originally created in the frontend in `LinkingState`, and previously it was only used internally in the frontend. It would make its way via `QuerySetManager` to `QuerySet.getFilterFunc` where the actual filtering logic happened. Now most of that logic has been moved to a similar function in `common`. The new function works with a new interface `ColumnGettersByColId` which abstract over the different ways data is accessed in the client and server in this context. There's no significant new logic in the diff, just refactoring and wiring.
Test Plan: Expanded two `nbrowser/SelectBy*.ts` test suites to also check the contents of a downloaded CSV in different linking scenarios.

Summary:
In a selector table, when a selected row is filtered out of view, linked widgets should update based on the newly selected row.
There were a few bugs that contributed to this wrong behavior:
- Gridview wasn't subscribing to the current row id, and the row with id 'new' was being converted to the first row
- Cursor was keeping track of the currently selected row id, it was hiding a problem behind the proper rowIndex
- Undo/redo somehow leveraged the wrong rowId from the cursor during the position restore.
The `No data` text was also changed to be more meaningful.

Summary:
1. Introduces another highlight for link-selector rows, with the same color as
regular selection, and allowing to overlap with regular selection.
2. Don't show "secondary" cursors (those in inactive sections), to keep a single
cursor on the screen, since having multiple (which different in color) could
cause confusion.
3. An unrelated improvement (prompted by a new fixture doc) is to default the
active section to the top-left one (rather than the one with smallest rowId).
4. Another unrelated improvement (prompted by a test affected by the previous unrelated improvement) is to skip chart widgets when searching (previously search would step through those with an invisible "cursor").
Includes also tweaks for better testing on Arm-based Macs:
- Add support for TEST_CHROME_BINARY_PATH environment variable (helpful for a Mac arm64 architecture workaround)
- Remove unsetting of SELENIUM_REMOTE_URL when running headless (unlikely to affect anyone, and can be done outside the script, but interferes with the Mac workaround)
Test Plan: Added a new test case that cursor and linking-selector CSS classes are present or absent appropriately. Fixed test affected by the fix to default active section.

Summary:
This adds a UI panel for managing webhooks. Work started by Cyprien Pindat. You can find the UI on a document's settings page. Main changes relative to Cyprien's demo:
* Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables.
* Cell values that would create an error can now be denied and reverted (as for the rest of Grist).
* Changes made by other users are integrated in a sane way.
* Basic undo/redo support is added using the regular undo/redo stack.
* The table list in the drop-down is now updated if schema changes.
* Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation.
* Factored out webhook specific logic from general virtual table support.
* Made a bunch of fixes to various broken behavior.
* Added tests.
The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case.
I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error.
I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end. Sneaky.
Contains a migration, so needs an extra reviewer for that.

Summary:
Two summary table widgets that share a source table and have compatible groupby columns can be filter linked. This diff fixes a bug where this linking is broken when the source table is hidden by access rules. The source table data isn't needed for the linking, but its metadata is, and that metadata is censored by GranularAccess. To deal with this:
- `LinkConfig._assertValid` allows blank `tableId`s specifically for linking two summary tables.
- `LinkingState.filterColValues` gets the `colId`s of groupby columns from the summary table columns rather than the source table.
A closely related problem is that the titles of summary tables are incomplete when the source table is hidden, e.g. they just say `[by A]` instead of `Table1 [by A]`. To fix this, the raw view sections of source tables are 'uncensored' in GranularAccess.
Initially I also planned to uncensor the tableId of the source table, which seemed like a better and more general fix for the blank tableId problem. But several parts of client code use blank tableIds to know that a table should be hidden, so they were left as is.
Test Plan: Added an nbrowser test for summary table linking, and a server test for uncensoring the raw view section in GranularAccess.

Building:
- Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast.
- Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var.
- Grist-core continues to build using tsc.
- Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned
on, so that tsc accepts and enforces correct usage.
- Client-side code is watched and bundled by webpack as before (using esbuild-loader)
Code changes:
- Imports must now follow ES6 semantics: `import * as X from ...` produces a
module object; to import functions or class instances, use `import X from ...`.
- Everything is now built with isolatedModules flag. Some exports were updated for it.
Packages:
- Upgraded browserify dependency, and related packages (used for the distribution-building step).
- Building the distribution now uses esbuild's minification. babel-minify is no longer used.

Summary:
The problem manifested while filtering by a column, closing the filter
would change the set of rows visible on the table. This would happen
only for rare table.
What caused that problem was that the filter being edited was wrongly
applyed also to another column, so depending on the content of the
column, it would entail unexpected behaviour.
The cause of that wrong association, was a mistakingly comparing the
id of two different type of thing: column and view field. The problem
would manifest if in the same section there were a view fields with
same row id as the column being filtered.
What made that confusion possible is the `.fieldOrColumn:
ViewFieldRec|ColumnRec` property of the FileInfo object, which could
hold either a view fields or a column record and was initialized with
view fields or columns if view fields was not found (ie: hidden
column).
Solution was to make sure FieldInfo is initialized with ColumnRec
alwasy (even for hidden column).
I'm not sure what is the reason why FilterInfo needed to support both
column record and view field record in the past, but it looks like
this is not needed anymore.
As a followup commit I think it would be worth the effort to refactor
FileInfo to accept only ColumnRec.

Summary:
When two widgets are linked by same-record linking, and the source of that link is also filter-linked, then it will pick up default values from its own filter-link source, but the same-record-link target didn't. This fixes that so that default values are filled in intuitively.
Moved the logic of linkingState, linkingFilter, and getDefaultColValues from BaseView.js to LinkingState.ts and ViewSectionRec.ts. In particular getDefaultColValues is now a property of LinkingState which may be copied from the source view section for a same-record link.
Note that `ViewSectionRec.linkingFilter` no longer uses `computerBuilder` and thus doesn't ignore dependencies inside LinkingState any more. I couldn't figure out how to make `linkingFilter` a `pureComputed` (otherwise I get recursion errors) that ignores dependencies. In any case, it's now important to have a dependency on `srcSection.linkingState()` for `getDefaultColValues` to work correctly, so I think this is for the best.
