Delete torch::deploy from pytorch core

Pull Request resolved: #85953

As we have migrated torch::deploy over to https://github.com/pytorch/multipy, we can now delete it from pytorch core as ongoing development will happen there.

This PR was created due to syncing issues with #85443 which is where the review history can be found.
