[gtk+/client-side-windows: 185/284] Don't ignore native CROSSING_GRAB/UNGRAB events

    Don't ignore native CROSSING_GRAB/UNGRAB events
    
    These are sent when someone else grabs the pointer, and we don't
    want to miss these expose events. For instance, we missed enter
    and leave events on alt-tab.
    
    There were some issues with these wrt out-of-sync grab information
    in the client, but that should now be handled. So, it should work
    or at least be fixable if we find some bug.
