[FFmpeg-devel] [PATCH 5/5] avcodec/nvenc: Accept YUV444P10_LSB and YUV444P12_LSB content

12bit is implicitly truncated to 10bit as part of doing this, but we
already do that for P016 and YUV444P16.

I've bundled a single version bump and changelog entry in this change
to reflect the updates to all three of nvdec/nvenc/cuviddec.
