Support GID1 for VVM configs

This CL allows VVM configs to be specifed with Group identifier, which takes precedence over configs with only MCC/MNC.

TelephonyVvmConfigManger is renamed to DialerVvmConfigManger. It was created when VVM was still in telephony, and need to separate itself from the CarrierConfig app.
