Note that AYUV and AYUV64 formats will be used to expand format support, especially some packed YUV formats (e.g., Y410, YUY2) are common DXGI formats used for hardware decoder/encoder on Windows but those formats cannot be used as a render target. We need to handle them differently without pixel shader help, using compute shader for example. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1699>
