Add support for the m.replace and m.reference bundled
aggregations.
This should fix plenty of subtle client issues.
Threads are not included in the new code as they have
historically been written to the database. Replacing the
old system would result in issues when switching away from
continuwuity, so saved for later.
Some TODOs have been left re event visibility and ignored users.
These should be OK for now, though.
Also fixes:
- Transaction IDs leaking in event route
- Age not being set for event relations or threads
- Both of the above for search results
Notes down concern with relations table
What's missing? Being able to use separate rooms & lists for typing
indicators.
At the moment, we use the same ones as we use for the timeline, as
todo_rooms is quite intertwined. We need to disentangle this to get that
functionality, although I'm not sure if clients use it.
- Remove most usages of `update_membership` in favor
of directly calling the `mark_as_*` functions
- Store the leave membership event as the value in the
`userroomid_leftstate` table
- Use the `userroomid_leftstate` table to synchronize the
timeline and state for left rooms if possible
Adds two new toggles to the configuration, the first of which allows disabling the policy server checks entirely, and the second of which allows disabling checking events created locally. They're both enabled by default for maximum PS efficacy but allowing them to be disabled allows people who frequently cannot contact policy servers, for example those in censored countries, to be able to still use rooms with pace, allows single-user/trusted-only homeservers to disable the preliminary check on their own events, and also gives an escape hatch in case an issue like #1060 happens again, especially with MSCs not in FCP being moving targets.
In future, I think we should gate all MSC implementations behind config flags, even if they default to on.

**Does not yet work!** Currently, state resolution does not correctly resolve conflicting states. Everything else appears to work as expected, so stateres will be fixed soon, then we should be clear for takeoff.
Also: a lot of things currently accept a nullable room ID that really just don't need to. This will need tidying up before merge. Some authentication checks have also been disabled temporarily but nothing important.
A lot of things are tagged with `TODO(hydra)`, those need resolving before merge. External contributors should PR to the `hydra/public` branch, *not* ` main`.

This PR should be squash merged.
