Summary didGeneratePageLoadTiming is called flakily when Site Isolation is disabled

When Site Isolation is disabled, we don't clear the frames-with-pending-subresources map when navigating to a new page. This causes the didGeneratePageLoadTiming callback to be flaky when SI is disabled, since it can cause WebPageProxy to think that the newly committed page has outstanding subresource loads, when those loads are actually associated with the previous page.
