Simplify styleForRenderer to avoid confusion.  Callers in the SVG filter code thought "forRenderer" meant
        they would be given a style that corresponded to the RenderObject* passed in.  This is not what the code
        did though.  This patch removes the renderer argument and the Element subclass shadow implementation
        so that confusion like this can't occur again.
