Make QQuickWidget update inside a proxy widget

Performance will be bad but this allows having simple scenes in a
QQuickWidget embedded into a QGraphicsView (ouch).

This kind of setup is strongly discouraged but QWidget already has the
readback-based fallback for render(), so we only need to add the
update re-routing to the proxy widget.
