Reintroduce membership tables event stream ordering (#15128)
* Add `event_stream_ordering` column to membership state tables Specifically this adds the column to `current_state_events`, `local_current_membership` and `room_memberships`. Each of these tables is regularly joined with the `events` table to get the stream ordering and denormalising this into each table will yield significant query performance improvements once used. * Make denormalised `event_stream_ordering` columns foreign keys * Add comment in schema file explaining new denormalised columns * Add triggers to enforce consistency of `event_stream_ordering` columns * Re-order purge room tables to account for foreign keys * Bump schema version to 75 Co-authored-by: David Robertson <david.m.robertson1@gmail.com> Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>
