Check for locked screen in DisplayRotation and

disable rotation resolver when power save mode is enabled

Disable RotationResolver when the screen is rotation locked.
This fixes an issue where AiAiAutoRotate would run & print to logs
when screen rotation is locked. It also prevents smart auto rotate
from running when power save mode is enabled.

Test: local, enabled auto rotate & camera rotate then disabled
autorotate & checked AiAiAutoRotate didn't show up in logs,
by enabling power save mode and face detection then checking camera
rotation not working
