livedisplay: Add support for direct color balance control

 * We currently use the DisplayColorCalibration API for setting display
   temperature which makes a lot of guesses about what temperature
   the display really is. Some devices will support the new ColorBalance
   API (via QDCM or other mechanism), which offers a calibrated
   alternative. Add support for this, which will supercede DCC if
   available.
 * Additionally, define the available color temperature range as a
   set of overlayable values so this can be specified per-device.
   This range will be mapped to balance values using the power curve
   calculations in the new MathUtils class.
