Bug 360919 - [MSVC] preprocessor symbol __STDC__ always defined

Move the __STDC__ macro to the scanner configuration extension, where we can
differentiate compiler type. Only add it when compiler type is not MSVC.
This will miss the case where MSVC is compiling in C mode and /Za is used,
then __STDC__ should be defined but this is a much less common case and would be
addressed likely outside scanner configuration.
