Turn off Wifi before going into sleep

- To make kernel implementation simple, we turn off Wifi before going
into sleep.
- When a car is restarted or get out of sleep mode, the last Wifi state
is restored.
- Log is replaced by Slog.

Bug: 159840640
Test: Execute dumpsys car_service suspend && adb reboot, and check if
Wifi state is the same before and reboot the restart.
