RFR: 8330621: Make 5 compiler tests use ProcessTools.executeProcess [v2]

[Evgeny Nikitin]

> Said tests use simple `new ProcessBuilder` and its `start` method to start secondary processes.
> 
> As stated in [JDK-8174768](https://bugs.openjdk.org/browse/JDK-8174768), we try to have more information about started secondary processes and make the execution more controllable. This PR makes those tests use ProcessTools.executeProcess instead of using the `.start` method.
