Clear calling ID before using SensorPrivacyManager

This is needed because some methods of SensorPrivacyManager have been
gated by a system permission. As a result, we have to clear binder
caller identity before calling these methods so that they are executed
with the same level of privilege as the SensorService. Otherwise, if an
app A makes a request to the SensorService to set up a sensor data
connection and the SensorService needs to call SensorPrivacyService
e.g., to register for a mic toggle state listener, the SensorPrivacyService
will think that it's app A that is calling, hence failing the permission
check.
