Disable tagged names (#26479)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26479
This PR doesn't delete the code for them yet because it takes some effort to
determine what to delete. I will send a followup PR fully deleting
tagged names, but this PR disables their creation.
