[mutter/wip/carlosg/clutter-seat: 32/35] backends: Drop get_relative_motion_deltas() vfunc

    backends: Drop get_relative_motion_deltas() vfunc
    
    Just go ATM through backend checks, and looking up directly the
    native event data, pretty much like the rest of the places do that...
    Eventually would be nice to have this information in ClutterEvent,
    but let's not have it clutter the MetaBackend class.
