enabled some clang-tidy warnings for non-GUI code (#5679)

There are some clang-tidy warnings which cannot properly handle the
extensions used in the Qt code so the produce lots of false positives
and were previously enabled. With clang-tidy now offering the
possibility to inherit the parent configuration we can enable these
across the project and simply disable them for the GUI code.

No additional warnings were found as they were already fixed in earlier
commits without enabling the checks in question.
