cudacodec::VideoWriter: Add 10 bit YUV420 and YUV444 encoding

[cudawarped]

Currently cudacodec::VideoWriter only encodes 8 bit YUV input. This PR adds the capacity to encode 10 bit YUV input as well.

Discussed in this forum post.

Thank you again for taking the time to test this on your local machine, I know CUDA is a pain.

Regarding the error the 1080 doesn't support decoding of YUV444, see the Video Support Matrix.

The error message

Video codec is not supported by this GPU hardware video decoder refer to Nvidia's GPU Support Matrix to confirm your GPU supports hardware decoding of the video source's codec

isn't more specific because there are numerous reasons a video source isn't supported and the actual reason is not returned by the Video Codec API.

Support is checked by filling out the format information, calling cuvidGetDecoderCaps() checking the value of CUVIDDECODECAPS::bIsSupported. See cudacodec::video_decoder.cpp` and Querying decode capabilities for more info.

Looking at the console output, the above is confusing. Establishing the chroma format in the demuxer is redundant as this is overwritten when the video is parsed. I suggest to remove this from

opencv_contrib/modules/cudacodec/src/ffmpeg_video_source.cpp

Line 155 in d6767ed

FourccToChromaFormat(pixelFormat, format_.chromaFormat, format_.nBitDepthMinus8);

In addition to my previous comment I will update the error message to include the codec and chroma format. That is the new message for CUDA_Codec/YUVFormats.Transcode/2 will be

10 bit H.265/HEVC with YUV 444 chroma format is not supported by this GPU hardware video decoder. Please refer to Nvidia's GPU Support Matrix to confirm your GPU supports hardware decoding of this video source.
