Factor a PageLoadHistograms class out of RenderView.

No functional changes are intended.

This is in anticipation of using the new WebPerformance API:
http://trac.webkit.org/changeset/68141

My strategy is this:
1. In this patch, make the most minimal change possible to the Dump() method
   necessary to factor it out to a new class.
2. Add a new, temporary histograms which log the WebPerformance metrics which
   have an existing counterparts.
3. Once we understand any differences and are happy with the new metrics, rip
   out the old ones. This will allow more cleanup in RenderView and
   NavigationState.
4. Add new histograms for any interesting WebPerformance metrics which weren't
   previously available.
