Bring back USNF's scripts-only mode for older Android, but better

- do scripts-only mode automatically on Android < 8.0 since it doesn't support Zygisk and generally doesn't need a PIF module to pass at all
- clean up all unused files in scripts-only mode, and modify script behaviors for it, including allowing GMS on DenyList, and even add it if missing since it's necessary on some scripts-only configurations
- allow manually entering scripts-only mode by deleting the zygisk directory of the currently installed module and reinstalling
- intentionally don't alter the Enforce DenyList state, since we don't know what other modules are installed that might depend on it one way or the other, so leave that up to the user
