    stylesheet: Stop special casing GtkMenuButton styles
    
    Since https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4150, menu
    buttons propagate all of their style classes to their internal
    GtkButton, so we can stop special casing basically all of that.
    
    Drastically reduces the size of the compiled stylesheet.
