[gtk+] configure.ac: Consolidate gdk backend specific checks and code

[Kristian Høgsberg <krh src gnome org>]

    configure.ac: Consolidate gdk backend specific checks and code
    
    Only the big chunk of x11 checks is left further down in the file,
    but that depends on variables and checks above it, so we'll leave that in
    place for now.
