Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/43077
2 Bit Embedding weight conversion operation is quite similar to
4 bit embedding weight conversion.
The diff contains both the
1. 2bit packing op `embedding_bag_2bit_prepack`.
2. 2bit unpacking op `embedding_bag_2bit_unpack`.
Comments about the op are inline with the op definition.
Test Plan: buck test caffe2/test:quantization -- test_embedding_bag_2bit_unpack
