window: Add private API to hardcode the main GdkWindow for a GtkWindow

Browse Source 
This must be called while the window is not realized yet, and sets the
GdkWindow that will be used for the next GtkWindow's realize/unrealize
cycle. The GtkWindow takes ownership on the GdkWindow, and as such it
will be destroyed when the widget is unrealized.
