libavutil/hwcontext_{d3d11va, dxva2}: Support Y212/XV36 pixel format

Browse Source 
Use DXGI/D3DFMT 16bit pixel format to compatible with 12bit Y212/XV36
since there is no 12bit pixel defined in D3D11/D3D9.

Fix cmdline on Windows:

$ ffmpeg.exe -hwaccel qsv -init_hw_device qsv:hw,child_device_type=
{d3d11, dxva2} -i input_12bit.bin -f null -
