parentremove constantly lib use and switch to enums. (#12624) (diff)

Include bundled aggregations for the latest event in a thread. (#12273)
The `latest_event` field of the bundled aggregations for `m.thread` relations
did not include bundled aggregations itself. This resulted in clients needing to
immediately request the event from the server (and thus making it useless that
the latest event itself was serialized instead of just including an event ID).
