        [Resource Timing] Expose timing information for iframes
        https://bugs.webkit.org/show_bug.cgi?id=103927

        Reviewed by Nate Chapin.

        The only catch with main documents is that we only want to record the load that was initiated by
        adding the <iframe> to a document. We don't want any subsequent navigations within the iframe to
        be reported.

        Test: http/tests/w3c/webperf/submission/Google/resource-timing/html/test_resource_iframe_self_navigation.html

        (WebCore::CachedResourceLoader::loadResource):
