7904060: Enable profiler classes to be reused outside of JMH

[galderz]

This is the fourth in a series of PRs that I will be sending over the next few days, which make extending JMH to benchmark Java code running as GraalVM native images more easily. The codename for this extension is Fibula. It can still work without this PRs but without them the extension has to duplicate code that exists in JMH, which is not desirable.

This PR makes ProfilerOptionFormatter and ProfilerUtils classes public so that they can be reused by external profilers. An example of this usage can be seen in this perf dwarf profiler used for native image JMH benchmarks.

Here is the PR list for reference:

1. Make OutputFormatAdapter public
2. Enable BenchmarkParams construction to be overriden
3. Enable alternative Runner instantiation and Main reuse
4. Enable profiler classes to be reused outside of JMH
5. Enable JMH integration tests to be executed against other impls
