Summary:
Previously, ref/reflist columns were formatted entirely based on their visible column, since they received values from the visible or display columns rather than the actual row IDs. This creates `ReferenceFormatter` and `ReferenceListFormatter` which still delegate most of the formatting work to a visible column formatter but fix a few issues:
- ReferenceList columns now actually use the options (e.g. date format) of the visible column to format their elements. Previously they were formatted generically because the visible column formatter wasn't expecting a list.
- Invalid references aren't formatted with an `#Invalid Ref` prefix.
- When the ref column displays the Row ID, it doesn't have a visible or display column. Previously this led to the references being formatted as just numbers in most cases, with special code in the widget to display them like `Table1[2]`. Now they are consistently formatted in that style throughout.
Test Plan: Updated existing tests.

Two bugs fixed:
1. On search, when the first result is in the active record, GridView wasn't scrolling to the active record.
2. When an active record was not visible, GridView wasn't scrolling to the active record when the column index was changed.
The problem was that the scrolling behavior was based only on rowIndex which isn't changed (and doesn't notify subscribers) when a column index changes or when the search highlights a cell.
This diff makes the computed depend also on the fieldIndex, and is introducing a new method that can scroll to the active record on demand (which is used by the search).

Summary:
Some things (like rendering cells) use the `visibleCol` for `createFormatter`, while other things (like `CopySelection`) used the `displayCol`. For references, the display column has type Any and doesn't know about the original formatting. This resulted in formatting being lost when copying from reference columns even though formatting was preserved when copying from the original (visible) column which looked identical. This diff fixes this and ensures that `createFormatter` is always used with the `visibleCol`. This was agreed on in https://grist.slack.com/archives/C0234CPPXPA/p1639571321043000
Additionally:
- Replaces the functions `createVisibleColFormatter` computed properties `visibleColFormatter` as suggested by a `TODO`.
- Extracts common code from `createVisibleColFormatter` in `ColumnRec` and `ViewFieldRec`

Summary:
Added a new object type code `l` (for lookup) which can be used in user actions as a temporary cell value in ref[list] columns and is immediately converted to a row ID in the data engine. The value contains the original raw string (to be used as alt text), the column ID to lookup (typically the visible column) and one or more values to lookup.
For reflists, valueParser now tries parsing the string first as JSON, then as a CSV row, and applies the visible column parsed to each item.
Both ref and reflists columns no longer format the parsed value when there's no matching reference, the original unparsed string is used as alttext instead.

A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted.
This diff deals with getting the header in place. There will be more work to do after this:
* Make sure that all important endpoints are checking origin. Skimming code, /api endpoint check origin, and some but not all others.
* Add tests spot-testing origin checks.
* Check on cases that authenticate differently.
