60e503d4 - [dtensor][6/N] change to a better/safer op registration (#90735)

[dtensor][6/N] change to a better/safer op registration (#90735) This PR changes the op registration to a better mechanism, now we require the directly overload registration instead of the op key str, this have several benefits: 1. We ensure that the op registration registers the correct op, which means it would be faild if the op registration become wrong (this PR already fixing several op registration errors as we use direct OpOverload registration 2. If the overload name get changed/deleted, we immediately know it at the source code compilation level, which is safer 3. This also keep it consistents with the op registration mechanism with other tensor subclasses within PyTorch Differential Revision: [D42876250](https://our.internmc.facebook.com/intern/diff/D42876250) Pull Request resolved: https://github.com/pytorch/pytorch/pull/90735 Approved by: https://github.com/XilunWu, https://github.com/fduwjj
