Introduce DynamicDisplayInfo

In this CL we introduce the getDynamicDisplayInfo call
on ISurfaceComposer which replaces the existing
 - getDisplayModes
 - getActiveDisplayMode
 - getColorModes
 - getActiveColorMode
 - getHdrCapabilities

This way all display properties can be queried atomically.

The current DisplayInfo class is moved to the androd::ui
namespace and it's renamed to StaticDisplayInfo.

ui::DisplayMode is now LightFlattenable and the mode ID is
int32_t instead of size_t in order to prevent serialization
problems.

Additionally we add the ID field to ui::DisplayMode. This
way we no longer need the supported display IDs to be
from 0 to N-1.
