    Use gtk_doc=false to disable gtk-doc for meson builds
    
    disable_gtkdoc=true was just a guess by me at how this option might be
    named by projects. GNOME is standardizing on gtk_doc=false and that's
    what we'll use here. If you call it something else, set it manually in
    the module's mesonargs.
