Change idleness according to screen status

- Unlike DeviceIdlenessTracker, CarIdlenessTracker didn't listen to
screen status change.
- android.jobscheduler.cts.DeviceStatesTest#testDeviceChangeIdleActiveState
fails due to the above reason.
- It is natural to exit idle when screen is turned on, unless forced idle
is set or car is in garage mode.
