new 41d8d12cc2 avcodec/nvenc: accept P012/P212/YUV444P12MSB input

avcodec/nvenc: accept P012/P212/YUV444P12MSB input (truncated to 10-bit)
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_YUV444P12MSB (12-bit 4:4:4)
for high-bit-depth content, but nvenc rejected them:
nvenc_map_buffer_format()
returned NV_ENC_BUFFER_FORMAT_UNDEFINED, so a pipeline such as
"-hwaccel cuda -i 12bit.mp4 -c:v hevc_nvenc" failed with EINVAL.
NVENC has no native 12-bit encode format. As is already done for the
16-bit inputs (P016, YUV444P16, GBRP16), accept the 12-bit formats and
map them to the 10-bit NVENC buffer formats, truncating the two least
significant bits: P012 -> YUV420_10BIT, P212 -> P210, YUV444P12MSB ->
YUV444_10BIT. They are added to the supported input format list and to
the IS_10BIT / IS_YUV444 / IS_YUV422 helpers accordingly.
