Seungha Yang 5c3879ace6 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
