Add shortcut suggestions for rooms, remove then when leaving (#5180)
* Report shortcut usage for outgoing messages
This patch adds support for creating and pushing dynamic
long-lived shortcuts for outgoing messages. This together
with an existing reference to the roomId used by the
shortcuts as an identifer allows conversations to be
prioritized.

* Simplify how to get the other user in a DM room
* Add initial avatar icons to shortcuts
* Remove room shortcuts when they're no longer joined
* Try using API 33 for the new tests. They worked locally with API 30, so it's weird the CI asks for a higher API version.
* Add observers for the pin code and session logout states. With this we can prevent new shortcuts from being created and remove existing ones when needed.
* Wrap all calls to `ShortcutManagerCompat` with `runCatchingExceptions` to avoid crashes
* Make `DefaultNotificationConversationService` a singleton.
