Distinguish between a decoder being entirely missing and a decoder which
requires features which are not present in the incomplete implementation
in libavcodec and therefore can't be used.
Fixes#10759.
It can happen in H.264, MPEG2, VC1 that the current frame resource
memory is already in ref_resource. For example, for a interlaced frame,
the same curr memory is passed twice. For the second time it could possibly
reference itself. When this happens the curr is already given an index and
in ref_resources. When the reference frame index is required, we should check
the existance in the ref_resources first before assigning a new index for it.

Previous assertion was not useful. Now a warning is added to replace it.
For get_surface_index, we should return a zero index in case the index is not found.
But a warning is necessary to notify.

The implementation is based on:
https://learn.microsoft.com/en-us/windows/win32/medfound/direct3d-12-video-overview
With the Direct3D 12 video decoding support, we can render or process
the decoded images by the pixel shaders or compute shaders directly
without the extra copy overhead, which is beneficial especially if you
are trying to render or post-process a 4K or 8K video.
The command below is how to enable d3d12va:
ffmpeg -hwaccel d3d12va -i input.mp4 output.mp4
