Revert "[TSAN] Add __tsan_check_no_mutexes_held helper (#69372)"
The new lit test fails, see comment on the PR. This also reverts
the follow-up commit, see below.
> This adds a new helper that can be called from application code to
> ensure that no mutexes are held on specific code paths. This is useful
> for multiple scenarios, including ensuring no locks are held:
>
> - at thread exit
> - in peformance-critical code
> - when a coroutine is suspended (can cause deadlocks)
>
> See this discourse thread for more discussion:
