Obtains a reference to the promise object.
The behavior is undefined if *this does not refer to a coroutine whose promise object has not been destroyed.
This function is not provided for the specialization std::coroutine_handle<>.

The promise object of a no-op coroutine is not destroyed as long as there is some std::noop_coroutine_handle referring to the coroutine.
