Oh how can I save the arguments? Like where should I put the attributes? Like create a C++ Operation->Attribute map and re add them after the pass

We have `sdy::TensorShardingAttr`s that we attach to mainly function inputs/outputs and StableHLO custom calls with the name `sdy.sharding`. Unfortunately here I discovered we also need to attach them to `CallOp`s, and that wasn't being preserved :/
