Fix compilation of oneDNN with C++20 on Windows

[ilya-lavrenov]

Summary

oneDNN and some software which uses it (e.g. OpenVINO), are distributed as source code.
And some users may want to compile it with their own C++ standard and compile flags.

Problem statement

oneDNN with GPU backend enabled cannot be compiled with C++ 20 with MSVC compiler.
Build logs are https://github.com/openvinotoolkit/openvino/actions/runs/10289707118/job/28478073165

Problematic place https://github.com/oneapi-src/oneDNN/blob/main/src/gpu/intel/jit/gemm/include/internal/utils.hpp#L22 - __cplusplus is defined to 1997 value for MSVC compiler.

Preferred solution

Please, enable C++20 support om compilation level.

oneDNN should be buildable with C++ 20, so this looks like a bug. Relevant error message:

@rjoursler Looks like this line needs to take into account __cplusplus.

@rjoursler Looks like this line needs to take into account __cplusplus.

No, as I stated in the description:

Problematic place https://github.com/oneapi-src/oneDNN/blob/main/src/gpu/intel/jit/gemm/include/internal/utils.hpp#L22 - __cplusplus is defined to 1997 value for MSVC compiler.

You need to rely on _MSVC_LANG for MSVC compiler instead of __cplusplus

WA on OpenVINO side is to use https://learn.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-170, but we want to avoid it.

This should be fixed by commit ece6802, @ilya-lavrenov could you please confirm this issue is fully resolved?
