Add a setVideoSink() method to QGst::Ui::GraphicsVideoSurface to allow the use
of a pre-existing qtvideosink element

The GraphicsVideoSurface class creates a qtvideosink element on demand to bind
to a QGraphicsView. The API doesn't allow using a pre-existing qtvideosink
created independently from a GraphicsVideoSurface. For example one cannot bind
to an element created with QGst::Parse::launch. The proposed patch adds a
setVideoSink() method to GraphicsVideoSurface to provide this flexibility.
