[SurfaceFlinger] Decouple color management from wide color display property.

Previously, device is only color managed when the display is wide color gamut
display. This patch decouples this logic out so that device can have color
management even if it only has calibrated sRGB display.

BUG: 111505327
Test: Build, flash and check all color settings.
