Add strong mode color temp configs

- Create configs for low/highlightambientcolortemp
- Create configs for low/highlightBrightness
- Create configs for low/highlightBias
- Use different values, based on whether strong mode is enabled

Bug: 265233091
Test: adb shell dumpsys color_display | grep mTemperatureMin -A10 && adb shell dumpsys display | grep mLowLightAmbientBrightnessToBiasSpline -A2
Test: atest AmbientLuxTest
