Set emulator to use automotive specific health hal

Add an example battery health HAL that returns stubbed
values. This will allow apps to get a logical
battery stat value when querying via BatteryManager.

When correctly installed, health service will be
named android.hardware.health-service.automotive
instead of android.hardware.health-service.example.

Bug: 325636299
Test: adb shell ps -e | grep android.hardware.health
