Various AIX tests pass on Node 22, fail on later versions

[sxa]

A sibling issue to #61441
After clearing up some of the flakiness and machine-specific problems that were occurring on AIX it became noticable that there were some failures that were NOT failing when run against Node 22.

This issue is to continue the analysis and determine if the failures are from changes in the test cases or functional changes in the Node that caused the intermittent failures in later releases.

The RUN_TESTS parameter of the stress test that I was using to experiment with is sequential/test-watch-mode-restart-esm-loading-error wpt/test-streams async-hooks/test-emit-after-on-destroyed node-api/test_threadsafe_function parallel/test-repl-preview - The test-emit-after-destroyed one is a reasonably common flake on AIX and has been marked as such. wpt/test-streams is the other one that shows a slightly lower failure rate (around 1%) on the later versions.

Sample runs showing the differences - each of these ran 100 times on each of four AIX machines:

• Stress#654 on main: 18/400 failures
• Stress#655 on v25.x: 15/400 failures
• Stress#656 on v24.x: 13/400 failures
• Stress#657 on v25.x: No failures

A note on main on test-osuosl-aix72-ppc64_be_4: tools/test.py --repeat 2000 async-hooks/test-emit-after-on-destroyed had two failures out of 2000, both near the end of the run. Both occurred in this line. The test code is the same on v22.x and main. and the failure is that it gets a SIGILL on that line.

For wpt/test-streams it gave an error 1 time out of 200 - CRASHED (Signal: 5) saying Check failed: ptr == address.
