misra: Add support for expected suppressions in header files in `-verify` mode (#3252)
This commit allows to specify expected suppressions in the included
header files. This is necessary to verify MISRA checkers, which make
requirements for header files. For example, Rule 8.2 requires adding
prototypes for each function to the header files.

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/

misra.py: Treat enum constants as constant known at compile time (#2823)
C89 standard defines enum members as enumeration contants at ch.
6.4.4.3, and they are always known at compile time.

This commit fix false positives for rule 18.8 (and possible other rules
that check "constentess") with enumeration members.
