quantization: fix scale+zp serialization of quantized BatchNorm{2|3}d (#70432) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/70432 Scale and zero_point need to be buffers for serialization to work on them properly. This PR moves them to buffers. This is BC breaking, but the "before" state was completely broken (scale + zp were not serialized at all) so there is no value in trying to handle it. Test Plan: ``` python test/test_quantization.py TestStaticQuantizedModule.test_batch_norm2d_serialization python test/test_quantization.py TestStaticQuantizedModule.test_batch_norm3d_serialization ``` ``` python test/test_quantization.py TestStaticQuantizedModule.test_batch_norm2d_serialization ``` Imported from OSS Differential Revision: D33330022 D33330022 Reviewed By: jerryzh168 Pulled By: vkuzo fbshipit-source-id: 673c61f1a9f8f949fd9e6d09a4dbd9e5c9d5fd04
