Apply "printf format" to APIs

[AaronRobinsonMSFT]

There are APIs throughout the codebase that accept printf-style-formats. Now that our internal printf implementation has been removed, #81243, these APIs should be marked appropriately so the compiler can validate them.

Examples

runtime/src/coreclr/utilcode/stresslog.cpp

Line 788 in cd3f357

void ThreadStressLog::LogMsg(unsigned facility, int cArgs, const char* format, ...)

runtime/src/coreclr/jit/error.cpp

Line 362 in cd3f357

int logf(const char* fmt, ...)

runtime/src/coreclr/md/compiler/regmeta.cpp

Line 839 in cd3f357

int DumpMD_VWrite(_In_ _In_z_ const char *str, ...)
