[server] Implement the generic window property in QtSurfaceExtension

Browse source 
Summary:
Qt supports setting generic data on a QWindow. This change implements
the callback properly and forwards the property to the surface extension
instance. This allows the compositor to e.g. listen to
DynamicPropertyChangeEvents and get access to all additional set
properties.
