[caffe2] update the BlobSerializer acceptor to allow moving in the data (#60207) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/60207 Update the `BlobSerializerBase` API so that the serizialized blob data is passed as a `std::string&&` rather than `const std::string&`. This allows the acceptor to take ownership of the string data. This allows the acceptor to do things like queue it for storing asynchronously, rather than having to make a copy of the data if they need it to remain valid after returning. All existing `BlobSerializerBase` implementations already pass in a valid rvalue reference to the data, so this change did not require updating any of the existing serializer implementations. ghstack-source-id: 132216750 Test Plan: Examined all ~46 `BlobSerializerBase` subclasses in fbsource to confirm they already pass in an rvalue reference for this argument. Also searched for `BlobSerializerBase` on google and did not find any external references to this class in other open source projects that might be affected.
