RFR: 8307307: Improve ProcessTools.java to don't try to run Virtual wrapper for incompatible processes [v2]

[Leonid Mesnik]

> The ProcessTools has some support of jtreg thread factory functionality.
> It tries to run the new process using virtual thread to run `main()` method.
> This fix updates it to skip the java runs where no main class is involved and more correctly process options which has 2nd argument.
> Also is sets `main.wrapper` property to allow launched process understand id any wrappers is used.
