Revert 249523 "telemetry: Use browser compositor rendering stats..."

Reason for revert: The HasRenderingStats method in Python that this change added is calling a non-existent method (see http://build.chromium.org/p/chromium.perf/builders/Mac%2010.8%20Perf%20%282%29/builds/2827). Is also on the blamelist for http://build.chromium.org/p/chromium.perf/builders/Win%207%20Perf%20%281%29/builds/11758 which is the first red build on that bot.
