[package] fix torchscript classes in package (#68028)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68028
Today, we demangle a typename before passing it to the TorchScript
compiler. This breaks compilation of torch classes in cases where we are
attempting to script the same class name from inside a package and out,
since we will return the same qualified name for both.
