These were introduced in #15782.

There was a race where the deleting of rows in worker_read_write_locks_mode could race with an insert. The triggers are trying to ensure that there is a single row in worker_read_write_locks_mode corresponding to any row in worker_read_write_locks with the same lock name/key. The fix is to only delete rows in worker_read_write_locks_mode that have matching tokens (so we don't delete any new rows), and ensure that we always update worker_read_write_locks_mode when we insert (to lock the table to stop races against deletes).

The first commit has the change in the trigger, the second commit moves the change to a new delta so that any existing triggers get properly updated.

Fix bad merge of #15933 (#15958)

This was because we reverted the bump of the schema version, so we were not applying the new deltas.
