* Add `WakeLock` to dismiss ringing call screen when call is cancelled
We had already some checks in place to automatically cancel a ringing call notification/screen when the call was no longer active, but the `RoomInfo` updates weren't being processed because the app was 'paused'.
The partial wakelock should ensure these room info updates are handled.
* Add mutual exclusion to `ActiveCallManager` methods to improve thread safety
Breaking changes addressed:
* Make `MatrixClient.getNotificationSettings()` async, cache its result.
* Use `RoomInfo` for accessing the updated room's info.
* Refactor `MatrixRoom` so it always receives an initial `MatrixRoomInfo` value: this value will be used to make `MatrixRoom.roomInfoFlow` a `StateFlow` so we can assume the initial updated Room data will be present.
* Fetch encryption state when loading a room if it's unknown
* Add Google Tink dependency, replacing `androidx.security.crypto`
* Replace the `EncryptedFile` implementation too
* Extract constants, add some more docs
* Use `Settings.System.DEFAULT_RINGTONE_URI` for ringing notifications
This replaces `RingtoneManager.getActualDefaultRingtoneUri`, it should get the same audio file and avoid some reported issues about not having permission to load the audio file.
* Create `SyncOrchestrator` to centralise the sync start/stop flow through the whole app: the decision is based on several inputs: sync state, network available, app in foreground, app in call, app needing to sync an event for a notification.
* Make network monitor return network connectivity status, not internet connectivity
* Don't stop the `SyncService` when network connection is lost, let it fail instead. This prevents an issue when using the offline mode of the SDK, which made the wrong UI states to be shown when the `SyncState` is `Idle` (that is, after the service being manually stopped).
* Rename `NetworkStatus.Online/Offline` to `Connected/Disconnected` so they're not easily mistaken with internet connectivity instead
