  [run-benchmarks] Use `ktrace artrace` for profiling browser benchmarks

Reviewed by Dewei Zhu.

Up until now, the `--profile` argument in run-benchmarks hasn't done anything. This patch implements profiling using the `ktrace artrace` command.

The --profile argument has been modified to require a TRACE_TYPE argument, this can be either `full` or `profile`. It'll start profiling when the test starts, and save the resulting files to the directory specified in --diagnose-directory (or /tmp/ by default).
