Fall back to CPU copies for srgb textures in copy_texture_CHROMIUM. The copied data is not supposed to have sRGB conversions applied to it when written to the destination texture but an sRGB SRV is used by Blit11. Instead of creating multiple sRGB and non-sRGB SRVs for textures, simply fall back to the CPU copy path for this format for now. Clip color channels that should not exist in the destination texture formats in Image11::CopyImage. This works around issues with texture formats with emulated channels.
