ea24a2e527 d3d11: Add support for packed 8bits 4:2:2 YUV formats
Note that newly added formats (YUY2, UYVY, and VYUY) are not supported
render target view formats. So such formats can be only input of d3d11convert
or d3d11videosink. Another note is that YUY2 format is a very common
format for hardware en/decoders on Windows.

f9f6916aa1 d3d11window: Reorganize display colorspace selection
The set of supported color space by DXGI is not full combination of
our colorimetry. That means we should convert color space to one
of supported color space by DXGI. This commit modifies the color space
selection step so that d3d11window can find the best matching DXGI color space
first and then the selected input/output color space will be referenced
by shader and/or d3d11videoprocessor.

a967db3b20 d3d11format: Add util methods for mapping DXGI color space with ours
Move color space mapping and hdr10 metadata conversion methods to
d3d11format in order to reuse the code.

96f0f4b613 d3d11memory: Always use native DXGI format if device support it
Use consistent memory layout between dxva and other shader use case.
For example, use DXGI_FORMAT_NV12 texture format instead of
two textures with DXGI_FORMAT_R8_UNORM and DXGI_FORMAT_R8G8_UNORM.

49a1f022fd d3d11colorconverter: Handle P016_LE format
P016 format is no different than P010. Not much things to add code.

6c3311a39e d3d11: Refactor d3d11 memory and dxgi format usage
* Create staging texture only when the CPU access is requested.
Note that we should avoid the CPU access to d3d11 memory as mush as possible.
Incoming d3d11upload and d3d11download will take this GPU memory upload/download.

* Upload/Download texture memory from/to staging only if it needed, similar to
GstGL PBO implementation.

* Define more dxgi formats for future usage (e.g., color conversion, dxva2 decoder).
Because I420_* formats are not supported formats by dxgi, each plane should
be handled likewise GstGL separately, but NV12/P10 formats might be supported ones.
So we decide the number of d3d11memory per GstBuffer for video memory depending on
OS version and dxgi format. For instance, if NV12 is supported by OS,
only one d3d11memory with DXGI_FORMAT_NV12 texture can be allocated by this commit.
One use case of such texture is DXVA. In case DXVA decoder, it might need to produce decoded data
to one DXGI_FORMAT_NV12 instead of seperate Y and UV planes.
Such behavior will be controlled via configuration of GstD3D11BufferPool and
default configuration is separate resources per plane.
