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.
