msm8974-common: libril: Handle MCC/MNC in data registration state provided by legacy vendor RILs

Include MCC/MNC provided by legacy (versions 14 and older) vendor RIL
implementations as part of data registration state, in data registration
state reported to clients of the radio HAL service.

Bug: 119904357
Test: local build and did the local test on Marlin device,
      the mcc/mnc value are correct (not -1 and empty string value).

[haggertk: This purposely omits updating the numStrings check in
 getDataRegistrationStateResponse(), given that we purposely changed
 that check in our libril]
