Doze - remove metrics logger, add uievent

- UiEvent wasn't being used onWakeScreen even though the events
themselves already exist. Use ui-event and add event for wake timeout
- Inject UiEventLogger for easier testability

Test: manually view ui events using command
  `$ANDROID_HOST_OUT/bin/statsd_testdrive-terse 90`
Test: atest DozeTriggersTest
