feat: update APU tests to synchronize with P4 ISA and add APU primitives filelist checks

Browse Source 
- Modified test_apu_register_parity.py to reflect changes in P4 ISA definitions.
- Updated test_apu_register_parity.py to include new manifest entries for P4.
- Enhanced test_script_tools.py to include checks for APU primitives filelists.
- Added assertions for APU primitives in the formal filelists test to ensure proper scoping and inclusion.
