radeonsi/vcn: Return error when decoding 12bit VP9 and 4:2:2/4:4:4 AV1

Browse source 
This is not supported by VCN.
We indicate this limitation by not reporting YUV420_12 RT format
supported for VP9, and not reporting YUV422 and YUV444 for AV1.
Most applications however simply ignore this, and will pick some other
format that is supported, which obviously won't work.
