RFR: 8334886: jdk/jfr/api/recording/time/TestTimeMultiple.java failed with RuntimeException: getStopTime() > afterStop

[Erik Gahlin]

Could I have a review of a PR that fixes an intermittent failure. I have not been able to reproduce the failure after running the test 10 000 times, but it does reproduce quite easily without the fix. 

It could be that the method awaitUniqueTimestamp() could be removed completely with the introduction of a similar method in https://github.com/openjdk/jdk/pull/19799 (which happens before the chunk rotation), but I rather fix it separately. 

I want this change to be suitable for a backport to JDK 23 and without additional regressions. 

Thanks
Erik
