Pull Request Overview

This PR removes a test case for the permissive mode in the C++ CodeQL library, along with its expected output files. The change appears to be cleaning up test files after extractor changes made the permissive mode test obsolete.

• Removes the permissive.cpp test file containing a function with const-correctness issues
• Removes the corresponding expected output files for calls and accesses queries

Does the rest of the test (e.g. non_permissive.c) still have value?

I believe so. I think it's good to know that it still fails (as it should).
