Add COLOR_MODE_AUTOMATIC

COLOR_MODE_SATURATED disables color management and thus treat any
color space as panel color space.  COLOR_MODE_AUTOMATIC is similar

color space, but the stretching is color space aware.

persist.sys.sf.native_mode is extended to be a integer, where

 0: use DisplayColorSetting::MANAGED
 1: use DisplayColorSetting::UNMANAGED
 2: use DisplayColorSetting::ENHANCED
