Use wide gamut color grading and gamut mapping (#4524)

* Use wide gamut color grading and gamut mapping This change introduces a new API on ColorGrading to enable or disable gamut mapping at will. This feature is currently off by default and while useful and recommended, it isn't cheap and we need to figure out what we want our defaults to be especially on mobile targets. Gamut mapping can be combined with luminance scaling to properly control hue skews. * Small cleanup * More precise Rec.2020 conversion
