Clean up charger's libhealthd dependency.
- Charger uses libhealthloop to maintain an infinite
loop, similar to all health 2.x services.
- Charger tries to open up health 2.1 HAL implementation
to retrieve health info. If it failed, it falls back
to the legacy code path where a default BatteryMonitor
is used, *except* that it won't depend on libhealthd's
healthd_board_init() and healthd_board_battery_update()
anymore.
- Remove global static variables because they are hard to
track.
- Modernize code by converting charger_state in to a C++
Charger class, transforming all functions into methods,
and moving all other global states into the class.
- Devices that matches all of the following:
- have a customized libhealthd (search for modules
named libhealthd.xxxx)
- uses charger from system image (look for "class charger"
in device init.rc scripts; if you see the binary is named
"/charger" or "/system/bin/charger" then you are using
charger from system image)
... must implement health 2.1 passthrough implementation
properly in order to have charger continue to work.
See hardware/interfaces/health/2.1/README.md for details.

much more information and is easy for health HAL impl
to use it.
Also add getHealthInfo* functions for health HAL
implentations to use.

Converting charger to Soong, one step at a time.
In the meantime, drop the use of BOARD_*/TARGET_* variables
in Android.mk because runtime sysprops will be used instead.
Libraries / binaries will always link to libminui / libpng /
libsuspend.
charger{.recovery,} can't be converted to Soong yet because
of the use of HAL_STATIC_LIBRARIES (Bug 127677771).
charger_test isn't converted because of the shared list
of CHARGER_{STATIC,SHARED}_LIBRARIES.

This CL splits out healthd_mode_charger_nops for building
charger.recovery. It doesn't change the functionality of the charger
module under recovery, i.e. a) it still doesn't do much work other than
reporting the battery status periodically; b) it keeps calling
device-specific healthd functions (healthd_board_init and
healthd_board_battery_update) via the statically linked HAL.
Previously `charger -r` was used to indicate starting charger under
recovery mode. This CL makes it a noop since we've changed the caller in
recovery.

This encourages device manufacturers to use
service.override over service and to remove healthd

(cherry picked from commit 2db565d75f)
Removes healthd from the build if -service.override
is provided. This encourages developers to deprecate healthd
for their devices when they can.
When -service.override is used, framework manifest needs
to remove the /backup instance as well; this can be done
by including manifest_healthd_exclude.xml in
DEVICE_FRAMEWORK_MANIFEST_FILE.

This is the original code path (BatteryService
-> healthd -> health 1.0 HAL). This ensures
upgrade-ability for old devices to P.
