Add Falcon-7B HuggingFace model

[petermcaughan]

This PR adds two features to torchbenchmark:

1. Include tiiuae/falcon-7b model from HuggingFace in torchbenchmark suite.
2. Include code path to pass arguments from model's __init__.py into model constructor during benchmarking. Running Falcon-7B in HuggingFace requires the parameter trust_remote_code to be passed.
   • There are two files that are executed when Falcon is loaded: configuration_RW and modelling_RW that both contain what seem to be safe code related to modeling specifics.

Can we have a link to upstream code that reference the train batch size?

[petermcaughan]

The Falcon README shows the training batch size to be 2304 [link] - updated comment to reference this. This seems prohibitive to run in testing suite though, so I kept the default size to 4.

[xuzhao9]

Thanks for making the reference! We should use the per-device batch size here. In the link it mentioned 2304 batch size on 384 A100 GPUs, so per-GPU batch size should be 6. Can you please update it to 6 and add the link ( https://huggingface.co/tiiuae/falcon-7b/blob/main/README.md#:~:text=Batch%20size,tokens%20ramp%2Dup) as the reference?

[petermcaughan]

Thanks for the clarification! Updated the size and the reference link.
