[TensorPipe/RPC] Serialize and deserialize message (#36197)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/36197
Create APIs to convert between rpc::message and tensorpipe::message
1. tensorpipeSerialize() - converts rpc::message to tensorpipe::message without memory copy (tensors).
2. tensorpipeAllocateMessage - allocates rpc::message based on received tensorpipe descriptor to prepare memory-copy-free receiving.
