* Add prefs to limit threadpool sizes
Add preferences to control the size of threadpools,
so that we can easily reduce the amount of runtime
threads and test which pools benefit from more
threads.

* Add pref for Webrender threadpool
Add a preference to limit the size of the webrender threadpool.
Note: WebRender by default calls hooks which register the threads with
a profiler instance that the embedder can register with webrender.
Servo currently doesn't register such a profiler with webrender,
but in the future we might also want to profile the
webrender threadpool.
