perf: improve async op santizer speed and accuracy (#20501)
This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
