d3d11videosink: Add new Direct3D11 video render plugin Direct3D11 was shipped as part of Windows7 and it's obviously primary graphics API on Windows. This plugin includes HDR10 rendering if following requirements are satisfied * IDXGISwapChain4::SetHDRMetaData is available (decleared in dxgi1_5.h) * Display can support DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 color space * Upstream provides 10 bitdepth format with smpte-st 2084 static metadata

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.
