RFR: 7903676: JMH: Simplify GHA pipelines [v2]

[Aleksey Shipilev]

> JMH currently runs many jobs with matrix taking the optional profile. This means many jobs are not actually doing any useful work. When those jobs run, we have quite a few warnings: "Error: Path Validation Error: Path(s) specified in the action for caching do(es) not exist, hence no cache is being saved."
> 
> We can merge current pipelines a bit to simplify the whole thing.
