Enhance existing ECBM CL to also include domain specific ECBM logic

This CL does a couple of things:
- Cleans up some linting errors
- Speeds up testing the EmergencyStateTracker test by reducing
  timeouts during testing and reducing scope of hidden variables.
- Uses new CarrierConfigManager API vs old one to speed up config
  transactions over Binder
- Fixes a bug where using a test number would cause the Radio response
  to never complete. We also now clear the mIsTestEmergencyNumber
  variable once the emergency modes are exited.
- Enhances the code to take into account the domain that the
  emergency call is currently placed over. This is important for
  ECBM because we perform different procedures based on domain
  selected.
- Added some logging.

Test: atest EmergencyStateTrackerTest; placed/received call/sms/data
