Faster joins: check how incoming events are authed during the partial-state phase #12644
Description
I/we need to revisit how incoming events are authed while we lack full state. When I was testing, it looked like we were relying on Synapse's unspecced _update_auth_events_for_auth behaviour. If we're going to rely on that, we'll have to understand it and spec it.
A subtask of this is to figure out if we need power events upfront (eg, banned users) to get reliable state.

Did we not decide that we should try ripping the
_update_auth_events_for_authcode out?richvdh commentedon May 16, 2022
We talked about it back in a previous tranche of event-auth work (see #9595 (comment) etc), but I think we decided we needed to convince ourselves it wasn't important, first. The work for #9595 ended up significantly simplifying it, and documenting its interface a bit, but never got as far as completely ripping it out.
The problem we have now is that the faster-joins work appears to be relying on
_update_auth_events_for_auth, so we now need to re-consider whether we still want to rip it out, or do something else for faster-joins.
