Adds a ruff lint rule to ban raising raw exceptions. Most of these should at the very least be runtime exception, value errors, type errors or some other errors. There are hundreds of instance of these bad exception types already in the codebase, so I have noqa'd most of them. Hopefully this error code will get commiters to rethink what exception type they should raise when they submit a PR.
I also encourage people to gradually go and fix all the existing noqas that have been added so they can be removed overtime and our exception typing can be improved.

Summary:
Kineto traces use microsecond level granularity because of chrome tracing defaults to that precision. Fix by adding preprocessor flag to TARGETS and BUCK files. Also remove any unnecessary ns to us conversions made in the profiler itself.
This diff contains profiler changes only. Libkineto changes found in D54964435.
Test Plan:
Check JSON and chrome tracing to make sure values are as expected. Tracing with flags enabled should have ns precision. Tracings without flags should be same as master.

There are known issues with profiling cuda graphs - particularly, if you create a cuda graph before the first use of the profiler, and then run that cuda graph during profiling.
One workaround is to add `with profile(): pass` before creating the cuda graph that you want to profile later.
For convenience, we provide this function to use the workaround. This also adads a test for this workaround, to ensure that it continues working.

Approved by: https://github.com/Chillee, https://github.com/aaronenyeshi
Test Plan:
Add test in test_profiler.py to check idle time computation.
To test the heuristic, we use serialized real world data stored in test_profiler_utils_golden.py to ensure a run to run stable test.
