cmd/cgo: generated headers are incompatible with the latest C++ standards in MSVC 

The current cgo-generated headers are not compatible with MSVC when using ISO C++ 17 or later.

These headers rely on constructs that are deprecated or removed in newer C++ standards, leading to compilation errors.

This issue affects projects using modern C++ versions and requires either downgrading the C++ standard or manually modifying the generated headers.

Fixes #71921
