* Move GL context object to GstNVDecoder object, and remove duplicated handling of each codec decoder element * Don't create GL context too early. We can create it only if we need to negotiate with downstream gl element. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2089>
