Added HF use-case benchmark script (linkedin#223)

## Summary
- Added Hugging Face training benchmarking script used for tech report
- Writes files to
`/results/${MODEL_TYPE}_use_liger_${USE_LIGER}_batch_size_${BATCH_SIZE}_rep_${i}.log`

## Testing Done
- Ran benchmarking script

- Hardware Type: A100
- [x] run `make test` to ensure correctness
- [x] run `make checkstyle` to ensure code style
- [x] run `make test-convergence` to ensure convergence
