Summary:
Adding support for 2-way references in data engine.
- Columns have an `reverseCol` field, which says "this is a reverse of the given column, update me when that one changes".
- At the time of setting `reverseCol`, we ensure that it's symmetrical to make a 2-way reference.
- Elsewhere we just implement syncing in one direction:
- When `reverseCol` is present, user code is generated with a type like `grist.ReferenceList("Tasks", reverse_of="Assignee")`
- On updating a ref column, we use `prepare_new_values()` method to generate corresponding updates to any column that's a reverse of it.
- The `prepare_new_values()` approach is extended to support this.
- We don't add (or remove) any mappings between rows, and rely on existing mappings (in a ref column's `_relation`) to create reverse updates.
NOTE This is polished version of https://phab.getgrist.com/D4307 with tests and 3 bug fixes
- Column transformation didn't work when transforming RefList to Ref, the reverse column became out of sync
- Tables with reverse columns couldn't be removed
- Setting json arrays to RefList didn't work if arrays contained other things besides ints
Those fixes are covered by new tests.

Summary: Mostly just changes to tests to make them more flexible.
Test Plan: Python tests pass locally with 3.10 and 3.11. Making tests run in CI on these versions will happen in grist-core.

Summary:
Dealing with some things that bothered and sometimes confused me:
Make Table.Record[Set] provide the table argument automatically
Remove the classes from UserTable because they're not used anywhere and the Table/UserTable distinction is already confusing. They're not documented for users and they don't show up in autocomplete.
Remove RecordSet.Record because it was confusing me where that attribute was being set, but also this means .Record will work properly for users with columns named 'Record'.
