Fix an issue that the sensor privacy does not apply to the new camera clients

The sensor privacy (Sensors Off tile) does not apply to the new camera
clients because the 'SensorPrivacyPolicy' in the 'CameraService' mixes
API usage for the camera privacy and the sensor privacy which are
'isToggleSensorPrivacyEnabled' and 'isSensorPrivacyEnabled'
respectively.

This patch will use the 'enabled' value to fix the issue.

Bug: 257426686
Test: manual test with 'Sensors Off' tile is enabled.
