Allow displaying only unread notifications (#7803)

* Allow displaying only unread notifications

Add `FeatureFlags.ShowAllActivityInRoomList` (enabled by default, to match the current behavior) that, when disabled, will display the unread messages of a room instead of unread notifications if no unread notifications are found

* Restore UI changes to the badges, `RoomSummaryRow` and `HorizontalFloatingToolbar`

* Fix `NavigationBarIcon`: use `BadgeBox` component.

* Adjust padding in `RoomSummaryRow` to 6.dp

* Fix other indicators not displaying a dot anymore

* Update screenshots
