[compiler-rt] [ctxprof][nfc] Remove redundant `SANITIZER_NO_THREAD_SAFETY_ANALYSIS` (PR #133784)

[Mircea Trofin via llvm-commits]

https://github.com/mtrofin created https://github.com/llvm/llvm-project/pull/133784

With the refactoring in PR #133744, `__llvm_ctx_profile_start_context` doesn't need to be marked `SANITIZER_NO_THREAD_SAFETY_ANALYSIS` because `tryStartContextGivenRoot` (where the bulk of the logic went) is.
