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
