Add read all messages feature (#7049)

* Add read all messages feature: read all messages using Client.markAllRoomsAsRead() method

* Move the 'mark all rooms as read' footer as part of the list item

* Replace `showMarkAllRoomsAsReadConfirmation` and its associated event with `MarkAllRoomsAsRead(val needsConfirmation: Boolean)` and a `AsyncAction.Confirming` state
