Add escape hatch due to STL change resulting in issues with binary compatibility.

https://github.com/microsoft/STL/wiki/Changelog
"Fixed bugs:

    Fixed mutex's constructor to be constexpr. #3824 #4000 #4339
        Note: Programs that aren't following the documented restrictions on binary compatibility may encounter null dereferences in mutex machinery. You must follow this rule:

            When you mix binaries built by different supported versions of the toolset, the Redistributable version must be at least as new as the latest toolset used by any app component.

        You can define _DISABLE_CONSTEXPR_MUTEX_CONSTRUCTOR as an escape hatch."
