2c1de3aa - Back out Dispatcher change that makes Messenger Desktop crash on M1 devices (#77414)

Back out Dispatcher change that makes Messenger Desktop crash on M1 devices (#77414) Summary: This change causes Messenger Dekstop to crash on M1 devices when the user enables background during the call. The change apparently causes the compiler to emit AVX instructions that are not supported by Rosetta. This is a surgical backout that only backs out the changes in C++ side, and not Python bindings which I believe are not shipped with Workplace Chat. Test Plan: Run the application and make sure that it doesn't crash when the background is enabled https://pxl.cl/23VSH Reviewed By: ezyang Differential Revision: D36358832 Pull Request resolved: https://github.com/pytorch/pytorch/pull/77414 Approved by: https://github.com/bigfootjon
