torch/distributed: move quantization ops to libtorch instead of libtorch_python (#77444)
Summary: This moves the distributed/c10d/quantization ops to libtorch instead of libtorch_python. Since they don't depend on Python this avoids the duplicate registration error from TORCH_LIBRARY when used in torch::deploy.
