        [Texmap] [Qt] Texture mapper initial implementation
        https://bugs.webkit.org/show_bug.cgi?id=47070

        Glue layer (WebCoreSupport) changes to allow connecting TextureMapper to a Qt PageClient, i.e.
        a QWebView or a QGraphicsWebView. This enables the new type, TextureMapperPlatformLayer, to be recognized both by
        the compositor and by the page client.
        Note that this is temporarily an opt-in, under USE(TEXTURE_MAPPER)

        No new tests: the existing tests under LayoutTests/compositing already cover this.
