Move GdkVisual parallel-implementable

It turned out no vfuncs were necessary. I've decided to move
the screen member up to GdkVisual, since it is the same in all
backends. The X11 backend subclasses now, to add the X members
that it needs to keep track of. GdkVisual and GdkVisualClass
are hidden now.
