Add an example jmh microbenchmark to perf test group

[smlambert]

As has always been in plan (see perf/README.md), we want to add some example microbenchmarks from the ones available in jmh-jdk-microbenchmarks.

Can use a jar file from mvn or some other known location

Close this enhancement issue as we are unlikely to get to it quickly. Can reopen when more likely to revisit.

Re-opening now as we may be able to enable some (into special.perf? with jdk11+):
