* Add pfm CI actions for bazel * Fix problems in unit test. * Undo enabling the CI tests for pfm - github CI machines seemingly do not support performance counters. * Remove commented code - can be revisited in github history when needed, and there's a comment explaining the rationale behind the new test code. --------- Co-authored-by: Andy Christiansen <achristiansen@google.com> Co-authored-by: dominic <510002+dmah42@users.noreply.github.com>
