wayland: add supporting for video processing.
Try to use VA/VPP processing capabilities to handle video cropping and additional rendering flags that may not be directly supported by the underlying hardware when exposing a suitable Wayland buffer for the supplied VA surface. e.g. deinterlacing, different color primaries than BT.601, etc.
