To support execution of JMH benchmarks via GraalVM native image binaries, BenchmarkParams contructions needs to be tailored in order to take advantage of JMH's benchmark execution plumbing.

For native images, BenchmarkParams values for jvm, jvmArgs, jdkVersion, vmName and vmVersion fields need to be adjusted.

JMH can enable this by converting `Runner.newBenchmarkParams(BenchmarkListEntry, ActionMode)` method from private to protected. Making this change requires `ActionMode` to be made public instead of package private.

The benefits of this change brings to the native image JMH use case can be seen here: https://github.com/galderz/fibula/commit/8fd8cf3f4eb1c6f37de7f807bfc697ef981a3e05#diff-601b6d98eff18db8a804efb415d515c3d397d42b9c982713b72c37bea2ebbf18
