    macos: support standard fullscreen
    
    This moves to standard fullscreen behavior for Gimp.
    
    Added benefit is that it no longer requires gdkquartz-cocoa-access.h
    which the Gtk team wish to stop supporting https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4303.
    
    Bug 756178 also no longer manifests, 
https://gitlab.gnome.org/GNOME/gimp/-/commit/cdc7542d46a6d3c6b2c223d14f63e7d29d9571ec
    so it is now safe to do.
    
    Finally, removes dependency on objective c in the app/display directory.
