Sets the chat_allowed_groups to staff (the old default) in the database for
people who already have chat enabled if they did not already change it.
The assumption is that most people who this applies to will be
upgrading from a version that has neither of these two PRs (
the other PR being #19116) to a version that has both of these PRs.
So, for existing site with chat enabled who haven’t set groups, we
want to persist the value which is more likely to match what that are
upgrading from (staff).
People who don’t yet have chat enabled should get the new value (TL1
and staff) when they do enable it.

Since the migration was added as a post migration, we'll try to add the constraint first, causing a NotNullViolation exception.
This only affects sites that were last deployed more than two days ago.

Makes ChatMessage.last_editor_id and ChatMessageRevision.user_id
NOT NULL since they are always filled in now and the last commit
had a migration to backfill this data.
This commit adds last_editor_id to ChatMessage for parity with Post in
core, as well as adding user_id to the ChatMessageRevision record since
we need to know who is making edits and revisions to messages, in case
in future we want to allow more than just the current user to edit chat
messages. The backfill for data here simply uses the record's creating
user ID, but in future if we allow other people to edit the messages it
will use their ID.
