Add new GStreamer plugin that consists of multiple elements 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 used by other GTK4 apps if they wish to integrate it. This commit adds new video sink that uses a new kind of memory as input, called `ClapperGdkMemory`. With it comes a simple dedicated memory allocator, buffer pool and a `clapperimport` element that converts system mapped memory frames into `GdkTextures` that are later passed in our `ClapperGdkMemory` for the sink to display.
