build: various improvements

- Use `#pragma once` for `cmake.config/config.h.in`
- Remove unused variable `CACHED_GENERATED_DIR`
- Reorganize and sort variables
- Introduce `STYLUA_DIRS` variable to ensure the `formatlua` and
  `lintlua-stylua` operates on the same files.
- Adjust variable scope to avoid using hacky directory properties.
- Add more necessary runtime files as test dependencies
