Release GL resources of ShaderEffectSource while we still have GL.
When a Window element is used, the QML window item is deleted before
the ShaderEffectSource component and the deleteLater to delete the
texture gets handled too late. We now register for the
sceneGraphInvalidated signal and release resources synchronously
while shutting down.
