Distinguish between normal and extension renderers while recording thread load metrics.
The Blink Renderer Scheduler uses ThreadLoadTracker instances to measure main
thread load for backgrounded and foregrounded renderers. It's useful to measure
the same for extension renderer processes as well, to study how they contrast
with normal renderers. But currently, the content layer doesn't have the
information to determine if the current renderer process is an extension
renderer.
This CL plumbs this information through the RenderThread, which owns the
RendererScheduler. The renderer process type is passed as an enum to the
RendererScheduler, which logs UMA for the same.
