Fork code changes into platform/ and module/ folders
The platform folder will have all changes reverted to their state before the refactoring to avoid any new behavior when flag is off or in intermediate releases like 25q1. Flag: build.release_ondevice_intelligence_module Bug: 376427781 Change-Id: Ie2293837116684da833980f85b49099bfffe44bf
