Descriptionpredictors: Add prefetching hit/miss histograms.
When the resource_prefetch_predictor triggers a prefetch, record how
many resources were used / not used (hits and misses), and the pattern
of these (in cache, or not in cache). For the resources that are not in
the cache, record the amount of data prefetched and wasted.
This also assumes that a prefetch older than 5 minutes is wasted.
