    wayland: Let MetaWaylandTabletManager process tablet events
    
    meta_wayland_tablet_manager_update()/handle_event() are called before
    the MetaWaylandSeat counterparts. If the event comes from a device
    managed by MetaWaylandTabletManager, the event will be exclusively handled
    by it.
