[llvm] Use reportFatalUsageError in llvm-omp-kernel-replay (PR #178371)

[via llvm-commits]

https://github.com/sladyn98 created https://github.com/llvm/llvm-project/pull/178371

All error cases in this tool are usage errors (bad user input, missing files, malformed JSON) rather than internal LLVM bugs, so `reportFatalUsageError` is the appropriate replacement.
