Now that the thread_times.__ benchmarks are merged into the rendering
benchmarks, remove benchmarks in thread_times.py and unnecessary
page set json files. Since oop_raster.py benchmarks use
thread_times._ThreadTimes, leave this for now.

Remove page_sets/polymer.py because it has been entirely replaced by
page_sets/rendering/polymer.py.
