null event NT handle to ID3D12Fence::SetEventOnCompletion() will block the calling CPU thread already, thus it has no point that creating an event NT handle in order to immediate wait for fence at CPU-side. Note that passing a valid event NT handle to the fence API might be useful when we need to wait for the fence value later (or timeout is required), or want to wait for multiple fences at once via WaitForMultipleObjects(). But it's not a considered use case for now. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7176>
