[torchrec] [composable] update ShardedEmbeddingBagCollection to be use registered EBCs with shardedTensors as registered modules (#758) (#88026) Summary: X-link: https://github.com/pytorch/torchrec/pull/758 This PR fixes a bug in FSDP/DDP, where ShardedTensors are not supported even if passed in as params to ignore. this is important for composability because TorchRec named_parameters() will return FQN of shardedTensors (as defined in goals) It defines device of ShardedTensor to be None when local_tensor() does not exist on rank update ShardedEmbeddingBagCollection to be composable according to https://docs.google.com/document/d/1TBJSd5zgEg6cRcXv3Okuj7bBkqQwGS2IPh4TLWNNzFI/edit Differential Revision: D40458625 Pull Request resolved: https://github.com/pytorch/pytorch/pull/88026 Approved by: https://github.com/wanchaol, https://github.com/rohan-varma
