Refactor structured set_output in Register{DispatchKey}.cpp (#62188) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/62188 These parts of the `set_output` code are identical for all operators in the kernel registration files. So, this moves them from being copied into every class to two helper functions at the top of the file.
