50c9e25251 [REFACTOR] health 2.0: healthd_common -> libhealthloop 
This change converts the original healthd_common.cpp to a
C++ class, HealthLoop, that manages the infinite loop in health-related
modules (charger, health HAL, healthd, etc.). By doing so, the global
static variables (including FDs and healthd_mode_ops) are cleaned up.

This helps us implement health HAL 2.1.

In order to support legacy modules (namely, healthd, charger, health HAL
2.0, which all depends on android.hardware.health@2.0-impl), a
healthd_common_adapter.cpp file is added to
android.hardware.health@2.0-impl, so that the following functions
in healthd/healthd.h continues to be implemented using the global
healthd_mode_ops:
    - healthd_register_event
    - healthd_battery_update_internal

Test: boot up the device and run VTS test on health HAL.
