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

A sibling issue to https://github.com/nodejs/node/issues/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

Start by running the listed RUN_TESTS cases repeatedly on AIX against Node 22 and later supported versions, using the linked stress-test results as comparison. Inspect sequential/test-watch-mode-restart-esm-loading-error, wpt/test-streams, async-hooks/test-emit-after-on-destroyed, node-api/test_threadsafe_function, and parallel/test-repl-preview. Done means determining whether each difference comes from test changes or functional changes in Node, while separating known AIX flakes.
