GP-654: Add SIM card-based carrier detection

This commit adds implementation of the SIM-based carrier detection.

The goal for this implementation is to replace various places in the firmware
that previously relied on the ICCID-based carrier detection, provide some layer
of abstraction and forward compatibility for such places.

It is particularly useful for fwSwitch radios with AUTO firmware selection capability.
