Add alert to encrypted rooms with visible history (Android). (#5709)

* feat: Add visible history alert to encrypted rooms.

- Adds a dismissable alert that is displayed whenever the user opens a
  room with `history_visibility` != `joined`. When cleared, this is
  recorded in the app's data store.
- When opening a room with `history_visibility` = `joined`, this flag is
  cleared.`
