WatchDog: support dumping AIDL HALs

Similar to how HIDL HALs are here, we don't know the commandline of the
service, so we can dump them based on service name prefixes.

Power stats and lights are added here, for parity w/ HIDL since these
hvae been converted to AIDL.

Fixes: 175322136
Test: after `adb shell am hang`, we can verify the light service is
  dumped, when it wasn't before:

  vsoc_x86_64:/data/anr # cat anr_2021-01-28-22-42-44-969  | grep light
  Cmd line: /vendor/bin/hw/android.hardware.lights-service.example
