wayland: Apply maximized and fullscreen state

We were just throwing the request away if the app asks to
fullscreen or maximize a window before it has been mapped.
This is something the GdkWindow API explicitly supports,
so make it work by saving the state until the surface exists.

This fixes things under weston. There are bugs in mutter
that keep this from working correctly with gnome-shell.
