migrating some straggler pytorch ops in fbcode to the new registration API (#48954)
Summary:
I already migrated the majority of fbcode ops to the new registration API, but there are a few stragglers (mostly new files that were created in the last two weeks).
The goal is mostly to stamp out as much of the legacy registration API usage as possible, so that people only see the new API when they look around the code for examples of how to register their own ops.
