[PyTorchEdge] Move all serialize/deserialize files to a separate target (#66805)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/66805

{F672465642}

DGW:
```
buck query 'allpaths(//xplat/caffe2:torch_mobile_core, //xplat/caffe2:torch_mobile_interpreter)' --output-format dot_compact | pastry
bunnylol dgw paste_id

```

Test Plan:
buck builds to pass

```
