Subject: [PATCH] mt: Make condition_variable::native_handle() conditional.
* According to the C++ standard, the presence and semantics of
std::condition_variable::native_handle (and native_handle_type) is
implementation-defined. E.g., starting with VS 2022 17.8, Microsoft's
implementation no longer provides them at all.
