Implement UI for history visibility acknowledgement. (#31156)
* feat: Implement UI for history visibility acknowledgement.

Shows a banner above the message composer whenever a user opens a room
with non-join history visibility, which they can dismiss.

- Whenever a user opens an encrypted room with non-join history
  visibility, show them a banner, unless we have already marked it as
  dismissed.
- Whenever a user opens an encrypted room with joined history
  visibility, we unmark it as dismissed.
