[mutter/wip/carlosg/crossings: 6/9] clutter/main: Add clutter_stage_repick_device() call

    clutter/main: Add clutter_stage_repick_device() call
    
    This is the very same code than meta_wayland_pointer_repick(),
    made part of Clutter, so triggering repicks on the same pointer
    coordinates is made easy.
    
    The intention is to remove meta_wayland_pointer_repick() in favor
    of this call.
