Add new GStreamer plugin with custom video sink for Clapper video player. The main difference is that unlike the old one, this does not operate using `GtkGLArea` anymore, but processes and displays `GdkTextures` directly through `GtkPicture` widget. Also this one is installed like any other GStreamer plugin, thus can be used via `gst-launch-1.0` binary or even by other GTK4 apps if they wish to integrate it. In order to not depend on GL stuff at build time, this plugin uses seperate GModules called "importers" in order to import different kind of memories into GdkTexture. This allows expanding its capabilities further then we were able to do before.
