Re-add benchmark tests

[ocelotl]

Benchmark tests were removed in #2999. There is an ongoing effort here to add new benchmarking infrastructure that would allow us to run these tests in separate hardware to make the results reliable.

Re-add benchmark tests along with a Github workflow that will run them in the new benchmarking infrastructure.
