Updated CISettings.py to use the edk2toolext codeql helpers (#414)

## Description

The 202311 rebase moved the codeql plugin from .pytool to Basetools.
This requires a change in CISettings.py to reference the correct codeql
helper functions. Instead of using the internal versions we instead move
to the edk2 pytool extensions version.
