Compress touch events in QQuickWindow.
Instead of sending multiple touch updates per frame, we
store the last one and flush the pending events just before
we enter into the scene graph sync phase.
[ChangeLog][QtQuick] QQuickWindow will compresses touch events
and delivers at most one touch event per frame.
