QPA: update backingstore also when moving QWindows
When moving QMdiSubWindows that contains native widgets (e.g QGLWidget)
inside a QMdiArea, garbage is drawn to the screen. The reason is
that since we use native QWindow backed widgets, QPA will assume
that it does not need to update/scroll the backingstore. But since the
backingstore can be shared among several windows, we need to do this to
ensure that exposed areas behind the moved QWindow will be updated.
