    core/events: Invalidate monitor cache when we're a wayland compositor
    
    When running as an X11 compositor we do this for every event we see on
    the X event stream. As a wayland compositor we don't go through that
    code path but since we see all events we can easily do this on motion
    events.
    
    In fact, we don't even need this caching when we're a wayland
    compositor since we can always find where the pointer is without a
    round trip but we're sharing the current monitor logic with the X
    path so let's keep it as is for now.
