* Separate thread notifications into their own notifications when the feature flag is enabled.
Otherwise, set the `threadId` to null so it'll behave as usual. It's done this way to avoid having to inject `FeatureFlagService` in several places.
* Add permalink navigation to threads from notifications, focusing on the latest event in the list of messages of the notification tapped
* Fix redactions in threads
* Clear notifications for a thread when visiting it
* Fix opening a thread happening twice, first because of the `openThreadId` value, then because of the `focusedEventId` one
* Make opening a room through a notification also focus on the latest event
* Add helper `NotificationCreator.messageTag` function
* Remove unused `ROOM_CALL_NOTIFICATION_ID`: `FOREGROUND_SERVICE_NOTIFICATION_ID`+ `ForegroundServiceType` is used instead
* Simplify `DefaultDeepLinkCreator`
* Make sure the main timeline focuses on the thread root id too when navigating to a thread
* Handle "Mark as read" action for thread notification, using `timeline.markAsRead`
* Log failures to mark rooms as read using the notification action
