cc: Plumbing for impl thread micro benchmarks
This patch adds plumbing for running micro benchmarks on the impl
thread. The concept is as follows:
- Create a main thread benchmark via gpu benchmarking extension
- On commit complete, if the benchmark provides an impl thread
benchmark, it is created and scheduled to be run on the impl thread
- Impl thread benchmarks are run after an appropriate callback
- Impl thread benchmarks post a done callback (with results) that is
run on the main thread
- The main thread benchmark gets the callback and posts its own done
callback (with aggregated results)
- This gets back to the gpu benchmarking extension which sends the
response back to the caller
