Araz Iusubov ccf073e772 avcodec/d3d12va_decode: enable reference-only mode ...

The Reference-Only feature in DirectX 12 is a memory optimization
technique designed for video decoding scenarios.
This feature requires that reference resources must be allocated with
the D3D12_RESOURCE_FLAG_VIDEO_DECODE_REFERENCE_ONLY resource flag.
Reference textures must also be separated from output textures.
This feature is not supported in the current version of ffmpeg.
Since AMD GPU uses this feature in Direct 12 decoder,
ffmpeg does not support AMD GPU Direct 12 decoding.
