[gtk+/wip/otte/gtk4: 27/127] API: window: Remove suppport for changing wmclass_name/group

[Benjamin Otte <otte src gnome org>]

commit 054463a13c3d5e2b1ab18cd1269c4c53ebbca8d0

    API: window: Remove suppport for changing wmclass_name/group
    
    X11 was the only backend to support it and people can just override it
    using XSetClassHint() directly.
    The docs already advertised the function as "Do not use".
    
    Keep the existing call to XSetClassHint() in place, so that we keep
    setting the same values as in GTK3.
