Add the byGroup option to have benchmark parameter grouping.
The environment variable NODE_RUN_BENCHMARK_GROUPS allows to benchmark
only certain groups: NODE_RUN_BENCHMARK_GROUPS=groupA,groupB.

Fixes: #26425

I think we should be adding something to the output (preferably in a "backwards-compatible" fashion) to indicate which group a particular configuration result is for, in order to remedy the issue noted in a previous PR that attempted to add similar functionality.
