        IDL changes for gamepad support

        https://bugs.webkit.org/show_bug.cgi?id=71753

        IDL changes and associated plumbing to expose list of gamepad objects

        on navigator object (per current spec). Full patch is

        https://bugs.webkit.org/show_bug.cgi?id=69451. Only basic existence

        test until more plumbing in future patches.
