This makes a few refinements to bundling widgets:
* A widget with `published: false` is not shown in the
custom widget dropdown in the UI. This is so widgets
can be bundled with the app for "native" use (like the
calendar widget) without immediately resulting in an
extra listing in the UI. (There are improvements we'd
like to make to the UI to better communicate widget
provenance and quality eventually, which would be a
helpful alternative to just a binary flag.)
* A relative path to the custom widget manifest is
respected. This will make the bundling process marginally
neater.
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.

This reverts the behavior of onOptions, which had unintentionally
changed recently and no longer matched the API documentation.

Summary:
Adding configuration options for CustomWidgets.
Custom widgets can now store options (in JSON) in viewSection metadata.
Changes in grist-plugin-api:
- Adding onOptions handler, that will be invoked when the widget is ready and when the configuration is changed
- Adding WidgetAPI - new API to read and save a configuration for widget.
Changes in Grist:
- Rewriting CustomView code, and extracting code that is responsible for showing the iframe and registering Rpc.
- Adding Open Configuration button to Widget section in the Creator panel and in the section menu.
- Custom Widgets can implement "configure" method, to show configuration screen when requested.
Test Plan: Browser tests.

Summary:
Exposing custom widgets as a dropdown menu in custom section configuration panel.
Adding new environmental variable GRIST_WIDGET_LIST_URL that points to a
json file with an array of available widgets. When not present, custom widget menu is
hidden, exposing only Custom URL option.
Available widget list can be fetched from:

Test Plan: New tests, and updated old ones.
