Drop jprocesses in favor of java.lang.ProcessHandle

[famod]

Description

As per #16249 (comment)

jprocesses has not seen any activity for 3 years and with JDK 8 support now dropped (in main), the OOTB ProcessHandle should be used instead.

Implementation ideas

Remove code, write a tiny bit of new code, remove dependency - be happy! 😉

Interesting, I didn't even know about jprocesses.

I actually had custom code for the IDE link handling that I just removed, so I'm obviously +1 for this

@famod fancy providing a PR?

I'm guessing the code in DevModeTestUtils would be something like:

    public static void killProcesses(String... cmdParts) {
        ProcessHandle.allProcesses()
                .filter(processHandle -> {
                    String cmdLine = processHandle.info().commandLine().orElse(null);
                    if (cmdLine == null) {
                        return false;
                    }
                    for (String part : cmdParts) {
                        if (cmdLine.contains(part)) {
                            return true;
                        }
                    }
                    return false;
                })
                .forEach(ProcessHandle::destroyForcibly);
    }

Looks like you implemented it already. 😄

[famod]

But yeah, I can provide a PR later this week.
