This PR uses the new `M_USER_LIMIT_EXCEEDED` common error code instead
of the malformed `M_RESOURCE_LIMIT_EXCEEDED` error code (as reported by
#18749) (spec: MSC4335).
The error code is also changed from `400` to `403` as this matches what
is in the spec for the endpoints:
https://spec.matrix.org/v1.18/client-server-api/#post_matrixmediav3upload
and
https://spec.matrix.org/v1.18/client-server-api/#put_matrixmediav3uploadservernamemediaid
(albeit the latter says that `M_FORBIDDEN` would be returned)
By default a new built-in `media_upload_limit_exceeded.html` template
will be served for the `info_uri`. Administrators can specify an
external URI in config instead.
Compatibility is retained for any existing modules making use the
`MediaUploadLimit` (e.g. via the `get_media_upload_limits_for_user`
callback).
This does two things, first it adds a config flag to ignore rooms for
the purposes of presence routing.
Secondly, it changes the caching behaviour to try and improve the cache
hit ratio. Previously, the size of the `do_users_share_a_room` cache
(which stores pairs of users) needs to `O(n²)` for the number of online
users, which is infeasible for large servers.
Instead, we call `get_users_in_room` for both the syncing and updated
users. This sounds more expensive, but a) we will already have cached
the syncing user's rooms, and b) we will only calculate the updated
user's rooms once (rather than once per syncing user).

Adds `last_active_granularity`, `sync_online_timeout` and `idle_timeout`
options to the `presence` config section, controlling the previously
hard-coded `LAST_ACTIVE_GRANULARITY`, `SYNC_ONLINE_TIMEOUT` and
`IDLE_TIMER` constants (which remain as the defaults).
This is mainly useful on deployments that ratelimit how often syncs can
affect presence (`rc_presence`): the sync timeout must exceed the
ratelimit interval or users flap offline between syncs, so tuning down
presence traffic currently requires squeezing under the fixed 30s limit.

There are a few improvements over the experimental support:
- authorisation of Synapse <-> MAS requests is simplified, with a single
shared secret, removing the need for provisioning a client on the MAS
side
- the tests actually spawn a real server, allowing us to test the rust
introspection layer
- we now check that the device advertised in introspection actually
exist, making it so that when a user logs out, the tokens are
immediately invalidated, even if the cache doesn't expire
- it doesn't rely on discovery anymore, rather on a static endpoint
base. This means users don't have to override the introspection endpoint
to avoid internet roundtrips
- it doesn't depend on `authlib` anymore, as we simplified a lot the
calls done from Synapse to MAS
We still have to update the MAS documentation about the Synapse setup,
but that can be done later.
