        Errors encountered within SVG documents should be reported to the console
        https://bugs.webkit.org/show_bug.cgi?id=62599

        Add SVGElement::reportAttributeParsingError, which will
        write a Web Inspector console message if passed an SVGParsingError
        and the attribute which was being applied, only in the case where
        there is actually an error.

        Include the SVG document's URI when writing to the Web Inspector
        console, so that the UI displays both the filename and the line number.
