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.

Load resources from /product/etc/res/{values,images}/charger. If a
resource fails, falls back to /res/{values,images}/charger.
If the device has GSI flashed, resources may exist in both paths.
Resources in /product is used with a higher priority.
Test: turn off device, charge, observe animation

Allow the charging animation to be customized with a configuration file
and custom assets.
- Add a parser to parse a custom configuration file.
- Add support for showing a clock and the battery percentage.
- Expand feature that conditionally shows animation frames using min_level
and level_only to min_level and max_level
