    windowMenu: Remove fallback app menu support
    
    With the app menu being phased out entirely, there's no good reason to
    keep support for the fallback app menu in decorations either - the number
    of applications that set an app menu and haven't embraced client-side
    decorations is extremely small, and they should already have alternative
    fallbacks for non-GNOME environment in place.
