7903781: Report the process id of the agent or other VM that was used for a jtreg action

[jaikiran]

Can I please get a review of this change which proposes to repor the process id of the process that was used to run a jtreg action? This change addresses https://bugs.openjdk.org/browse/CODETOOLS-7903781.

As noted in that linked enhancement request, this change will report the process id the section messages of each action. This will now look like:

#section:compile
----------messages:(7/297)----------
command: compile test/streams/FileDescriptorTest.java
reason: .class file out of date or does not exist
started: Fri Jul 26 00:56:01 UTC 2024
Mode: othervm
Process id: 88469
finished: Fri Jul 26 00:56:01 UTC 2024
elapsed time (seconds): 0.254

....

#section:main
----------messages:(7/232)----------
command: main FileDescriptorTest
reason: User specified action: run main FileDescriptorTest 
started: Fri Jul 26 00:56:01 UTC 2024
Mode: othervm
Process id: 88470
finished: Fri Jul 26 00:56:01 UTC 2024
elapsed time (seconds): 0.042

Notice the new "Process id: ..." line in those sections.
