Migrate misc from torch::deploy to multipy (#143)

Summary:
Pull Request resolved: #143

X-link: pytorch/pytorch#80213

We are creating a new repo called `fbcode/multipy` to house `torch.package` and `torch::deploy` code.

This diff migrates over `//caffe2/torch/csrc/deploy:xxx` usages over to `//caffe2/multipy/runtime` which is the new repo we are moving `torch::deploy` code to.

`test/cpp/api/imethod.cpp` still uses `torch::deploy` as it is used for OSS testing of `torch::deploy`
