Generalize the device IMEI display for IMEI/MEID and multi-SIM.

The user can initiate a call to display the IMEI device ID from the
dialpad. Since the code is almost identical for the IMEI/MEID cases,
factor out into one method. Also in the case where there is more than
one IMEI device ID (i.e. multi-SIM with multiple SIMs inserted), display
a list of IDs in order of slot number.
