Brian Osman 57ae6cfe01 Revert "Support decoding images to multiple formats, depending on usage"
This reverts commit c73a1ecbed.

Reason for revert: ANGLE and CommandBuffer failures

Original change's description:
> Support decoding images to multiple formats, depending on usage
> 
> Our codec generator will now preserve any asked-for color space, and
> convert the encoded data to that representation. Cacherator now
> allows decoding an image to both legacy (nullptr color space), and
> color-correct formats. In color-correct mode, we choose the best
> decoded format, based on the original properties, and our backend's
> capabilities. Preference is given to the native format, when it's
> already texturable (sRGB 8888 or F16 linear). Otherwise, we prefer
> linear F16, and fall back to sRGB when that's not an option.
