Enable quantizing local checkpoints in model release script (#2859)

Enable quantizing local checkpoints in model release script

Summary:
For torchao model release scripts, previously we only support quantizing models downloaded from hf directly
(with a model id), this PR turns it off by default and allows users to quantize a local checkpoint

Test Plan:
cd .github/scripts/torchao_model_releases/
./release.sh --model_id $LOCAL_MODEL_PATH --quants FP8
