[PyTorch] [Model Tracer] Refactor method bodies in various record function handlers into source (.cpp files) (#73321)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73321
Simple refactoring change to ensure that methods with large bodies don't show up in `.h` (header) files. Instead they should be in `.cpp` (source) files to prevent slowing down compilation speed.
