introduces compile-time format string verification for printf-style functions on MSVC
It does so by redefining key variadic functions with macros that trigger format checks at compile time using a
sizeof(printf(...))trick. The implementation is compatible with both C and C++ and avoids dependencies onSAL.h. Additionally, the functions are wrapped withextern "C"for C++ compatibility.(PR desc by copilut, less bad equivalent of #253)
