Use a no-warning registry for TensorPipe backends (#60457)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/60457
The "without warning" variants of the registry were introduced in https://github.com/pytorch/pytorch/pull/31126 to be used in Gloo for the exact same reason: we use a registry precisely so that backends can be overridden, no need to scare users with a warning.
