        Move all JS constructors from DOMWindow.idl files.
        Issue #195

        Reviewed by Antonio/Chang Shu

        Use Supplemental=DOMWindow in IDL file inside module/webcl to
        move this to module/webcl.
        Since we have DOMWindowWebCLEnvironment interface supplementing
        DOMWindow, adding the constructors to WebCL interface to the same.

        No new tests (OOPS!).

        * Modules/webcl/DOMWindowWebCLEnvironment.idl:
        * page/DOMWindow.idl:
