avfilter: add d3d12 deinterlace filter deinterlace_d3d12

Browse Source 
This commit introduces a video filter `deinterlace_d3d12` that provides
hardware-accelerated deinterlacing using the D3D12 Video Processor.

The filter supports:
 - bob and custom (motion-adaptive)deinterlace modes
 - frame-rate and field-rate output
 - automatic interlace detection

Sample command lines:

1. Software decode with hwupload:

    ffmpeg -init_hw_device d3d12va=d3d12 -i interlaced.ts \
      -vf "format=nv12,hwupload,deinterlace_d3d12=mode=default,hwdownload,format=nv12" \
      -c:v libx264 output.mp4

2. Full hardware pipeline:

    ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i interlaced.ts \
      -vf "deinterlace_d3d12=mode=custom:rate=field" \
      -c:v h264_d3d12va output.mp4
