Sebastian Dröge 4ad101b53b Use once_cell crate directly again
The glib crate does not depend on it anymore and also does not re-export
it anymore.

Also switch some usages of OnceCell to OnceLock from std.

Gtk 4 Sink & Paintable

GTK 4 provides gtk::Video & gtk::Picture for rendering media such as videos. As the default gtk::Video widget doesn't offer the possibility to use a custom gst::Pipeline. The plugin provides a gst_video::VideoSink along with a gdk::Paintable that's capable of rendering the sink's frames.

The Sink can generate GL Textures if the system is capable of it, but it needs to be compiled with either wayland, x11glx or x11egl cargo features.

Flatpak Integration

To build and include the plugin in a Flatpak manifest, you can add the following snippet to your json manifest:
