[PageLoadMetrics] Reenable AdsMetrics and handle case where navigation aborts

It turns out that a frame can abort and continue to load resources even if it
has no previous navigation. This happens if a doc.write overwrites the frame
navigation while the navigation is still provisional.

This CL now labels all finished frame navigations (regardless of success) and
removes an incorrect dcheck.
