  Speculation Rules: fix up navigation-timing values.
https://bugs.webkit.org/show_bug.cgi?id=300299

Reviewed by Alex Christensen.

This PR saves the NetworkLoadMetrics when a DocumentPrefetcher gets them and 
applies them to a document when it finishes loading and its URL matches a 
prefetched document.
It also simplifies the DocumentPrefetcher logic related to prefetched 
CachedResources.
