[gtk: 3/7] wayland: Move toplevel/popup/drag surface definitions higher up

[Matthias Clasen <matthiasc src gnome org>]

    wayland: Move toplevel/popup/drag surface definitions higher up
    
    We them up there, so that code higher up compared to where they are
    defined now can make use of them. Also add a few macros for type
    checking and casting.
