refactor: clean up and fix the cc test
- Add tests to ensure that RPATHs are not added in cc mode, which can cause some builds to fail. - Change cc.py to use pytest style - Instead of writing out all the flags, break the flags down into variables so that it's easy to read what each test is supposed to check. This should make cc.py more maintainable in the future.
