ECBM SystemProperty cleanup

- Add getEmergencyCallbackMode() method in the TelephonyManager.java
to get the boolean value for ECBM callback mode from the phone through
ITelephony.aidl/java interface

- Use the added TelephonyManager Api to replace the 'get' of
PROPERTY_INECM_MODE system property in the framework/base
