Summary:
This PR updates `torch::pickle_save` to use the new zipfile format introduced in #29232 and adds `torch::pickle_load` which can decode the zipfile format. Now that `torch.save/load` use this format as well (if the `_use_new_zipfile_serialization` flag is `True`), raw values saved in Python can be loaded in C++ and vice versa.
Fixes#20356

TODO
* Include module names in message, #22207 should make this easy
