API review : Updates the API for CallbackMode for call and SMS

This commit updates the API for CallbackMode for Call and SMS according
to the API council review.
API review comment:
1. subId should be spelled out in full as subscriptionId in method
   calls.
2. The EmergencyCallbackModeListener methods shouldn’t require
   permissions, it’s expected that only the registration method has
   the permission. The extra annotations can confuse the API.
