[mutter] constraints: Make meta_window_constrain take window geometry rects

[Jasper St. Pierre <jstpierre src gnome org>]

commit 2209eac2bf2a02a025f25b9e91414a2c9c2f3846

    constraints: Make meta_window_constrain take window geometry rects
    
    Remove extend_by_frame and unextend_by_frame. Use a dumb hack in
    window.c to translate into window geometry in back. We'll soon track
    all rectangles in MetaWindow in terms of the window geometry.
