surfaceflinger: compute color mode mappings on hotplug

Populuate DisplayDevice::mColorModes when a DisplayDevice is
created.

DisplayDevice::mColorModes is a map from any possible
Dataspace/RenderIntent to supported
Dataspace/ColorMode/RenderIntent.  This makes sure we never ask the
composer to use an unsupported Dataspace/ColorMode/RenderIntent
combination.

The map is populated on hotplug because we don't want to compute the
mapping on the fly at each frame.
