Set HW toggle states

Propagate HW toggle state from InputManagerService to SensorPrivacyManager.
Enable devices with 2-way (on/off) or 3-way hardware switches (on/mic-only/off)
 to control the microphone and camera privacy toggles state and behavior.

Devices map the hardware toggles GPIO to SW_MUTE_DEVICE
 and SW_CAMERA_LENS_COVER codes, which are handled by InputFlinger -> InputManagerService.
