[clutter/clutter-1.20] stage: Only compress consecutive touch events from the same sequence

    stage: Only compress consecutive touch events from the same sequence
    
    And get CLUTTER_EVENT_LEAVE out of the touch event compression logic, as
    touches are always implicitly grabbed. If no sequence check is done, only
    the last touch update would be emitted, even if multiple sequences got
    updated.
