Fence data could hold GstD3D12Device directly or indirectly. Then if it's holding last refcount, the device object will be released from the device object's internal thread, and will try join self thread. Delegates it to other global background thread to avoid self thread joining. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6042>
