7904058: Enable BenchmarkParams construction to be overriden

[galderz]

This is the second 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 enables BenchmarkParams construction to be overriden, in order to easily support JMH use case for benchmarking native images. The JIRA contains a detailed explanation. Having this PR in simplifies construction of BenchmarkParams instance. The changes galderz/fibula@8fd8cf3#diff-601b6d98eff18db8a804efb415d515c3d397d42b9c982713b72c37bea2ebbf18 demonstrate the simplification enabled by the changes here.

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
