        [Gtk] Find a way for WebKit to "announce" itself so that ATs can readily distinguish it from true Gtk/Gail

        The "announcement" is now made in the form of an object attribute
        associated with the AtkObject.

        * platform/gtk/accessibility/object-attributes.html: Added.
        * platform/gtk/accessibility/object-attributes-expected.txt: Added.
