and used planes accross compositions.

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.

Add DisplayHandle which is a typedef for int64_t. Use this type instead
of the HWC2 hwc2_display_t type.
Additionally, rename variable names to prefer `display_handle` over
`display_id`, since "DisplayId" is overloaded and carries a different
meaning in the Android framework.

CompositionStats struct is a copy of HwcDisplay::Stats and is extracted
from HwcDisplay as a prestep for supporting stats reporting beyond
dumpsys.
CompositionStatsProvider interface can be implemented by a class that
will poll all displays and return a display->CompositionStats map for
the cumulative stats for each display.
CompositionStatsTracker is a helper class that tracks the state of the
last queried stats and calculates the delta between the last stats and
the currently pulled stats. A Callback function can be passed into the
Report function which will be called for each display, with the
cumulative and delta stats as arguments.
