Display room invitation notification (#735)

* Notifications: Add some extra mappings so we keep the original contents and can pass it later to an UI layer

* Fix notifications not appearing for a room if the app was on that room when it went to background.

* Modernize how we create spannable strings for notifications, remove unneeded dependency

* Remove actions from invite notifications temporarily

* Add `NotificationDrawerManager` interface to be able to clear membership notifications when accepting or rejecting a room invite

* Fix tests

* Add comment to clarify some weird behaviours

* Address review comments

* Set circle shape for `largeBitmap` in message notifications

* Fix no avatar in DM rooms

* Fix rebase issues

* Add invite list pending intent:

- Refactor pending intents.
- Make `DeepLinkData` a sealed interface.
- Fix and add tests.

* Rename `navigate__` functions to `attach__`

* Add an extra test case for the `InviteList` deep link

* Address most review comments.

* Fix rebase issue

* Add fallback notification type, allow dismissing invite notifications.

Fallback notifications have a different underlying type and can be dismissed at will.

* Fix tests
