    In the main Skia API YCbCr Images are usually created by wrapping a BackendTexture.
    Such backend textures are, in turn, created by a backend-specific entry point like:
       BackendTextures::MakeVulkan(SkISize, const VulkanTextureInfo&, ...)
    where the VulkanTextureInfo contains additional YCbCr information. This API cuts right to
    providing the backend-specific YCbCr information (i.e., the VulkanYcbcrConversionInfo).
