[Site Isolation] https/wpt/resource-timing/crossorigin-servertiming.html fails
https://bugs.webkit.org/show_bug.cgi?id=313280
rdar://175553453
Reviewed by Ryosuke Niwa.
A cross-origin iframe's initial navigation should appear as a
PerformanceResourceTiming entry in the parent document's performance timeline.
Resource timing does not work in site isolation because
ResourceTiming::addResourceTiming() relies on document.parentDocument and
frame->ownerElement(), which are null in the Site Isolation case.
To address this problem, we send the ResourceTiming data to the parent WCP
via IPC in SubresourceLoader::reportResourceTiming().
Then the parent adds the information to the document's Performance
object through the new ResourceTimingInformation::addResourceTimingToDocument().
