[Profiler] Weaken ordering check during post processing.
Pull Request resolved: https://github.com/pytorch/pytorch/pull/78563
The profiler assembles a call hierarchy by replaying recorded events. There is an assert to ensure that the events form a well structured tree; however many of the inputs are from external sources and small differences (e.g. recording time in a lower precision) leads to traces which violate that assumption. For now this is acceptable; the post processing can handle resolving these descrepencies. As a result, I am relaxing the assert to only test event types where we expect the framework to be able to enforce these strong structural requirements.
