Add support for the new RoomList API (#1092)
* Add support for the new RoomList API Squashed commits: [8c2625a] Re-enable invites [339e59b5] Add automatic syncing restarts after entering the terminated state for whatever reason [b5498e96] Reimplemented room list state management and usage [8154b0cf] Fix visible rooms range setting after scrolling stops [5155c44d] Hook up initial loading idicator and session verification banner to room list service states [700a5a2e] Enable back room subscriptions, timeline listeners and unread notifications / counts [9df383bc] Enable last messages and timestamps, they don't crash on release builds [7c4da9da] Add back certain fields now that the "full room" is available [9f6534a7] Adopt interfaces to new RoomList API, untested as requests don't go to the right URL * Tweaks following code review * Bump the RustSDK to v1.0.76-alpha
