Yarr: Fix developer build with MinGW 64

Use the MinGW/Windows runtime specific printf formats for size_t, formats,
fixing:

3rdparty\masm\yarr\YarrInterpreter.cpp: In lambda function:
3rdparty\masm\yarr\YarrInterpreter.cpp:2128:24: error: unknown conversion type character 'z' in format [-Werror=format=]
             out.printf("%4zu", index);
                        ^~~~~~
3rdparty\masm\yarr\YarrInterpreter.cpp:2128:24: error: too many arguments for format [-Werror=format-extra-args]
cc1plus.exe: all warnings being treated as errors
