Fix too many resizes and move events for native widgets
When the QWidgetWindow receives a resize or move event, it should check
with the widget if its crect already has this geometry. if not then send
the resize or move event
Ideally events should be sent whenever the QWidgetWindow receives them.
QTBUG-42383 is created for this problem
