        Removed a use of markDOMObjectWrapper: DOMWindow
        https://bugs.webkit.org/show_bug.cgi?id=59260

        * bindings/js/JSDOMWindowCustom.cpp:
        (WebCore::JSDOMWindow::visitChildren): No need to mark explicitly, since
        we use the opaque roots system now.

        * bindings/js/JSNavigatorCustom.cpp: Ditto.

        * bindings/scripts/CodeGeneratorJS.pm: Added autogeneration for objects
        whose opaque roots are frames.

        * css/StyleMedia.h:
        (WebCore::StyleMedia::frame): Added an accessor for the sake of GC.
