Summary: X-link: pytorch/FBGEMM#4250 after all of the rebasing and landing, the trunk still missed some of the needed changes for checkpoint loading: * change `create_virtual_table_global_metadata` to respect local_weight_count on each rank, or just use the param size as number of rows on each rank * register register_load_state_dict_post_hook in ShardedEmbeddingCollection to let it ignore loading the weight tensor Differential Revision: D75843542 Privacy Context Container: L1138451
