e1c092fe - Changes to transition to generic API for ops with weight prepacking (#35010)

Changes to transition to generic API for ops with weight prepacking (#35010) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/35010 semantics. This PR moves all the xnnpack specific interfces to a generic interface. Accordingly removes xnnpac specific reference from API and some variable names. What has not yet changed: TODO: USE_XNNPACK is still used. This can be removed where no XNNPACK specific things are done. e.g., RegisterOpContext.cpp and xnnpack_rewrite.cpp. Also the filename and structure also remains. Some of the generic class definition can be moved non-XNNPACK specific folder. Test Plan: python test/test_xnnpack_integration.py Imported from OSS Differential Revision: D20526416 fbshipit-source-id: 2e1725345c44bbb26bdc448097a7384eca121387
