Daniel Marjamäki 04e9c13bc6 TemplateSimplifier; Better handling of c++17 fold expressions and c++20 concepts. 
c++17 fold expressions are simplified to a __cppcheck_uninstantiated_fold__ if they are not instantiated.

c++20 concepts are skipped/removed by Cppcheck and these will be enforced by the compiler.

fix daca2 gdcm template simplifier crash (#3221) 
This only fixes the crash. The templates that are instantiated are
correct but one template is left uninstantiated. Fixing the missing
instantiation is not easy and will be looked at later.

misra: Fixed a crash in rule 8.2 (#3208) 
Due to incorrect indentation, we return "None" instead of an empty list,
which causes the crash.

The problem was reported on the forum: https://sourceforge.net/p/cppcheck/discussion/general/thread/e146b8d779/
