Define _DISABLE_CONSTEXPR_MUTEX_CONSTRUCTOR (#21005)

microsoft/STL#3824 introduces constexpr mutex.
An older version of msvcp140.dll will lead to ```A dynamic link library
(DLL) initialization routine failed```.

This error can be encountered if using conda Python since conda packages
msvc dlls and these are older right now.

This PR disables the constexpr mutex so that ort package can work with
older msvc dlls.

Thanks @snnn for the discovery.
