Update on "[ao] making _is_activation_post_process private with BC"

HDCharles · HDCharles · commit 19971a90dfca · 2022-12-08T11:01:19.000-08:00
same function in observer and quantize, consolidated to a single function note: this is a recreation of D40709276 which caused severa breakages due to not maintaining BC for models with cached code with calls to the old function name Differential Revision: [D41793604](https://our.internmc.facebook.com/intern/diff/D41793604/) **NOTE FOR REVIEWERS**: This PR has internal Meta-specific changes or comments, please review them on [Phabricator](https://our.internmc.facebook.com/intern/diff/D41793604/)!
