We can't rely on the `GstGLContext` to stay alive and need to keep track of it. For that we keep track of the `GstGLWindow` in a weak reference to avoid a reference cycle, and get the corresponding `GstGLContext` whenever needed. With contributions from Nirbheek Chauhan. Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1697 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3729>
