[Issue]: Roctracer reports GPU Events Ending at Same Time Next Event starts

[sraikund16]

Problem Description

We notice that many of the events in Roctracer for a single GPU and single queue have a "tie". The first event ends at the exact same nanosecond the second one starts. This is a fairly innocuous bug but can skew kernel metrics if the times are not being reported correctly. Ideally there would be some buffer of nanoseconds between an event end and event start.

This seems to be a different problem than https://github.com/ROCm/roctracer/issues/104 as it seems to be some issue with granularity rather than mismatched timings.
