[PR] avutil/hwcontext_d3d11va: support native P016 format (PR #23552)

PR #23552 opened by Kacper Michajłow (kasper93)
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23552
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23552.patch

Map DXGI_FORMAT_P016 to AV_PIX_FMT_P016 and keep the 12-bit P012 as a
compatibility entry, matching how Y216 and Y416 already expose both their
native 16-bit and 12-bit variants.
