To be used with the new d3d11 hwaccel decode API.
With the new hwaccel API, we don't want surfaces to depend on the
decoder (other than the required dimension and format). The old D3D11VA
pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the
decoder configuration, and thus is incompatible with the new hwaccel
API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D
and an index. It's simpler and compatible with the new hwaccel API.
The introduced hwcontext supports only the new pixfmt.
Frame upload code untested.
Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with
heavy changes/rewrites.
Merges Libav commit fff90422d1.

P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using
two bytes per component.
It may, and in fact is most likely to, be used in situations where
there are less than 16 bits of data. It is the responsibility of
the writer to zero out any unused LSBs.
This way, Doxygen is happier as aliases are now grouped together, and
it never handled #define's in an enum well in the first place.
Y400A already exists as an enum assignment.
P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two
bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs.

The h264/hevc Annex E colour primaries table says that AVCOL_SPC_SMPTE170M is
similar than AVCOL_SPC_SMPTE240M. These two values are not similar than
AVCOL_SPC_BT470BG.

Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely
to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format
that is aliased to the older VLD variant.
This is an API change.
