Create a wrapped C data pointer. [CCreate]

(1) template <typename T, typename R>
constexpr std::unique_ptr<T, R (*)(T *)> ccreate(T* ptr, R(* deleter)(T*), T*) noexcept;

(2) template <typename T, typename F, typename R = std::invoke_result_t<F,T*>>
constexpr typename std::enable_if<std::is_convertible<F, R (*)(T *)>::value, std::unique_ptr<T, R (*)(T *)>>::type ccreate(T* ptr, F deleter, T*) noexcept;

(3) template <typename T, typename F, typename R = std::invoke_result_t<F,T*>>
constexpr typename std::enable_if<!std::is_convertible<F, R (*)(T *)>::value, std::unique_ptr<T, F>>::type ccreate(T* ptr, F deleter) noexcept(std::is_nothrow_move_constructible<F>::value);

Utilities to wrap legacy C data type pointers in std::unique_ptr with a custom deleter.
