wlr_xdg_toplevel: store pending fullscreen output 

Since the fullscreen request may be made before the toplevel's surface
is mapped, the requested fullscreen output needs to be stored so it
can be retrieved on map (along with the existing fullscreen property).

This commit makes the required changes for wlr_xdg_toplevel.
