RFR: 8288415: java/awt/PopupMenu/PopupMenuLocation.java is unstable in MacOS machines [v2]

[Manukumar V S]

> java/awt/PopupMenu/PopupMenuLocation.java seems to be unstable in MacOS machines, especially in MacOSX 12 & 13 machines. It seems to be a testbug as adding some stability improvements fixes the issue. It intermittently fails in CI causing some noise. This test was already problem listed in windows due to an umbrella bug JDK-8238720. This fix doesn't cover the Windows issue, so the problem listing in windows will remain same.
> 
> Fix:
> Some stability improvements have been done and the test has been run 100 times per platform in mach5 and got full PASS.
