sunfish: Build LiveDisplay 2.0 HAL

* Lets use the common solution, and change our supported
  interfaces while we're at it:
 * Our panel (by default) uses AOSP color profiles.
 * Our panel does get along with Color Calibration &
   Reading Mode, which are done SDK side, and require
   no HIDL manifest entries.
 * Our panel does get along with Picture Adjustment
   features, so leave IPictureAdjustment in place.
 * Our panel does get along with Adaptive Backlight
   features, so leave IAdaptiveBacklight in place.
 * AOSP declares `ro.vendor.display.foss` but we don't
   have support for IAdaptiveBacklight, so don't declare.
