        Make SVG PendingResources use RefPtr
        https://bugs.webkit.org/show_bug.cgi?id=43587

        Convert SVGDocumentExtensions::m_pendingResources to use a RefPtr for 
        pending elements instead of a raw pointer so that pending elements can't
        be freed prematurely.

        Test: svg/custom/use-invalid-pattern.svg
