        [Refactoring] Pass NodeRenderingContext to Node::rendererIsNeeded()
        https://bugs.webkit.org/show_bug.cgi?id=61114

        - Extracted NodeRenderingContext from NodeRendererFactory, giving separate files to it.
        - Changed signature rendererIsNeeded(RenderStyle*)
          to rendererIsNeeded(const NodeRenderingContext&).
          The style object is retrieved from NodeRendererFactory::style()
          This will allow rendererIsNeeded() to access contextual
          information like attaching phase and rendering-parent.

        No new tests. No behaviour change.
