This change adds a new CompositionAttributes struct which tracks information about a given composition as it is validated and subsequently presented. Previously CompositionStats were tracked as totals for each display. This change splits the stats according to the CompositionAttributes for each presented composition. This change only affects the reporting behavior of CompositionStatsTracker. The stats logged by DumpState are totaled so as to not be affected. Change-Id: I050cce7f63891971cc807b9c5150d9b5d30f1f0b
