C++: Usability of MISRA via GitHub CodeQL

[AlexanderLanin]

The setup of 'MISRA via GitHub CodeQL' is described at #185
What we need now is feedback from a C++ developer about usability.

e.g. does it produce good error messages? Is it fast enough? Can it replace classic tools like clang-tidy or cppcheck?

Bonus:

• Compare output to other tools

Out of Scope:

• License evaluation
• MISRA compliance evaluation
• Any safety evaluation
