avfilter/cuda: support P012/P212 and MSB 4:4:4 in scale/transpose/thumbnail
NVDEC and CUVID now output AV_PIX_FMT_P012 (12-bit 4:2:0), AV_PIX_FMT_P212
(12-bit 4:2:2) and AV_PIX_FMT_YUV444P10MSB / AV_PIX_FMT_YUV444P12MSB
(10/12-bit 4:4:4) for high-bit-depth content, but these CUDA filters
rejected the formats in their supported-format lists, breaking pipelines
such as "-hwaccel cuda ... -vf scale_cuda" on 12-bit input.
These formats use 16-bit sample storage, and the filters select their CUDA
kernel by byte-storage size and plane layout, not by the number of valid
bits, so they can reuse the existing 16-bit kernels:
- scale_cuda: P012/P212 -> "semiplanar16", YUV444P10MSB/YUV444P12MSB ->
"planar16".
- transpose_cuda: the ushort/ushort2 kernels are chosen from the pixel
descriptor (byte size + channel count); just allow the new formats.
- thumbnail_cuda: P012 reuses the P010/P016 path and the MSB 4:4:4 formats
reuse the YUV444P16 path; P012 is added to the 4:2:0 chroma-histogram
scaling as well. (thumbnail has no 4:2:2 path, so P212 is not added.)
The CUDA deinterlacers (bwdif_cuda, yadif_cuda) already accept any format
with <= 2 bytes per sample and <= 2 channels, so they need no change. The
8-bit-only filters (overlay_cuda, pad_cuda, bilateral_cuda, chromakey_cuda,
colorspace_cuda) do not support high bit depths and are left untouched.
