Add and use DisplayHotplugConnectModeDetectedAtomReporter, which logs
all valid modes of a hotplugged display.

Add DisplayRefreshRatesChangedAtomReporter, which reports the changed
refresh rates of all the active displays managed by drm_hwcomposer.

With the Backend concept expanding to also include the initial display
configuration and creation of DrmDisplayPipeline, rename the Backend
class to more precisely reflect its purpose.

This change adds fields for counting the total number of layers
and used planes accross compositions.
Change-Id: I7c2593f66f734a4f8ec8ddf7a2f6b5c0c8dc3cc3
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.

IStats service is started by system_server which is not running during
VTS tests. In this case, the IStats service is declared, but not
started, which may result in a hang when calling AServiceManager_waitForService.
Acquire the IStats client lazily when reporting atoms, and log an error
upon failure to do so. If IStats is declared, we should expect that the
service will be available under normal operation.
Another benefit of this approach is that acquiring the IStats service is
no longer blocking service initialization.

The IStats service provides an interface for reporting metrics from
vendor processes through the IStats::reportVendorAtom interface.
The type and ordering of the data in a VendorAtom are determined by a
proto definition which is typically OEM-specific. The code to construct
the VendorAtom is generated from the proto definition.
Add a soong config variable in the DRMHWC config namespace to enable the
atom reporting. Currently there is only one such implementation.
atom_reporter: Set this to configure OEM-specific atom reporting.
With the config variable omitted, reporting will be disabled and a stub
implementation is used, ensuring no build or runtime dependency or usage
of the IStats service.

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.
