marble: fix auto brightness after screen turn on

Browse Source 
After the screen has been off for a long time, when the screen is turned on, auto brightness is very slow to restore from 0.
I sensors-hal: handle_sns_std_sensor_event:65, light_event: ts=763376097432, lux: 0.0, extra_info=0
or when the screen is on
I DisplayPowerController[0]: BrightnessEvent: brt=0.0011033387 (8.0%), nits= 3.1000004, lux=0.0, reason=automatic

adb logcat | grep " lux"

added LightNotifier logic from https://github.com/LineageOS/android_device_xiaomi_sm8450-common/blob/lineage-22.2/sensors/sensor-n
