cc: Add MicroBenchmarkController plumbing.

This patch adds the necessary plumbing for micro benchmark controller.
The plan is as follows:

- MicroBenchmarkController will live on LayerTreeHost
- The schedule functionality will be exposed to
  gpu benchmarking extension
- Javascript bindings will allow external code to schedule certain
  benchmarks (specified by name) to be run right after Layer::Update.
