Add a (long) timeout to when a "busy" device is considered not online.
This does *not* match MSC3026, but is a reasonable thing for an
implementation to do.
Expands tests for the (unstable) busy presence with multiple devices.
Tracks presence on an individual per-device basis and combine
the per-device state into a per-user state. This should help in
situations where a user has multiple devices with conflicting status
(e.g. one is syncing with unavailable and one is syncing with online).
The tie-breaking is done by priority:
BUSY > ONLINE > UNAVAILABLE > OFFLINE
Refactoring to use both the user ID & the device ID when tracking
the currently syncing users in the presence handler.
This is done both locally and over replication. Note that the device
ID is discarded but will be used in a future change.
Refactoring to pass the device ID (in addition to the user ID) through
the presence handler (specifically the `user_syncing`, `set_state`,
and `bump_presence_active_time` methods and their replication
versions).
Simplify some of the presence code by reducing duplicated code between
worker & non-worker modes.
The main change is to push some of the logic from `user_syncing` into
`set_state`. This is done by passing whether the user is setting the presence
via a `/sync` with a new `is_sync` flag to `set_state`. If this is `true` some
additional logic is performed:
* Don't override `busy` presence.
* Update the `last_user_sync_ts`.
* Never update the status message.
Misc. clean-ups to:
* Use keyword arguments.
* Return early (reducing indentation) of some functions.
* Removing duplicated / unused code.
* Use wrap_as_background_process.
For now this maintains compatible with old Synapses by falling back
to using transaction semantics on a per-access token. A future version
of Synapse will drop support for this.

And fix a bug in the implementation of the updated redaction
format (MSC2174) where the top-level redacts field was not
properly added for backwards-compatibility.
**Before:**
```
Error retrieving alias
```
**After:**
```
Error retrieving alias #foo:bar -> 401 Unauthorized
```
*Spawning from creating the [manual testing strategy for the outbound federation proxy](https://github.com/matrix-org/synapse/pull/15773).*
We now only block the client to backfill when we see a large gap in the events (more than 2 events missing in a row according to `depth`), more than 3 single-event holes, or not enough messages to fill the response. Otherwise, we return the messages directly to the client and backfill in the background for eventual consistency sake.

* Check required power levels earlier in createRoom handler.
- If a server was configured to reject the creation of rooms with E2EE
enabled (by specifying an unattainably high power level for
"m.room.encryption" in default_power_level_content_override), the 403
error was not being triggered until after the room was created and
before the "m.room.power_levels" was sent. This allowed a user to
access the partially-configured room and complete the setup of E2EE
and power levels manually.
- This change causes the power level overrides to be checked earlier and
the request to be rejected before the user gains access to the room.
- A new `_validate_room_config` method is added to contain checks that
should be run before a room is created.
- The new test case confirms that a user request is rejected by the new
validation method.
