Added CellIdentityTdscdma for TDS-CDMA cell identity. Also added a base class for existing CellIdentityXxx so that the network service can return specific RAT cell identity through the network service callback API which takes generic cell identity as the parameter. This is the preliminary change for IWLAN refactoring since cell identity is part of the CS/PS network registration. bug: 64132030 Test: Unit tests Change-Id: I3ca405d687667b6c43e782339edec26a6f6edfc9
