- Converted VisibilityLoggerMixin into a LifecyclerObservable so we don't have to call logger.onResume/onPause manually in most fragments. - Observable will be useful when we provide logics across all fragment/activity, eg log lifecycle event latencies. - Also added new tests for lifecycle component. Bug: 30681529 Test: RunSettingsRoboTests Change-Id: Ida39300aeb42f71b2e0bbfaebd0c51dc468cb5e8
