Fix ambient information which did not get for locking refresh rate

Sometimes we will see  that the display state is ON but the
DeviceInteractive is false and then BrightnessObserver can not register
the light sensor.Hence, it can not judge if the threshold meets the
condition for blocking zones.This patch is for fixing this kind of
case.

Bug: 176018998
Test: atest DisplayModeDirectorTest
Test: no fps transition in the blocking zone when the display state change
Test: check if the lux will update when the display state change
