Add a per-room mutex to federationapi when processing transactions (#1810)
* Add a per-room mutex to federationapi when processing transactions

This has numerous benefits:
 - Prevents us doing lots of state resolutions in busy rooms. Previously, room forks would always result
   in a state resolution being performed immediately, without checking if we were already doing this in
   a different transaction. Now they will queue up, resulting in fewer calls to `/state_ids`, `/g_m_e`, etc.
 - Prevents memory usage from growing too large as a result and potentially OOMing.

And costs:
 - High traffic rooms will be slightly slower due to head-of-line blocking from other servers,
   though this has always been an issue as roomserver has a per-room mutex already.

* Fix unit tests

* Correct mutex lock ordering

Implement rejected events (#1426)
* WIP Event rejection

* Still send back errors for rejected events

Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.

* Implement rejected events

Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.

* Update test to match reality

* Modify InputRoomEvents to no longer return an error

Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.

* Remove redundant returns; linting

* Update blacklist
