Camera muting via sensor test pattern
Currently enabled/disabled via
adb shell cmd media.camera set-camera-mute <1/0>
TODO:
- Connect to the wider sensor muting feature
This is suitable for testing apps to see how they react, and how Pixel phones
implement test patterns.
Test: GoogleCameraApp and AOSP Camera2 on sunfish appear to act as if they were in a dark room,
no crashes, after calling 'adb shell cmd media.camera set-camera-mute 1'
