63105fd5 - Refactor CallbackManager as a nested class of RecordFunction. (#44645)

Refactor CallbackManager as a nested class of RecordFunction. (#44645) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/44645 Moved CallbackManager as a nested class of RecordFunction to allow private access to the call handles and context without exposing them publicly. It still hides the singleton instance of the CallbackManager inside record_function.cpp. Test Plan: Unit tests.
