shared-qmi: implement SIM/profile change detection

Browse Source 
Implement eUICC change detection for QMI based modems using one of the
following mechanisms (in order of preference):

1. If the modem supports "get slot status" operation, we monitor
   physical slot status indications from the modem for the active
   slot to detect when ICCID changes.
2. Use "refresh register all" to subscribe refresh indications when
   the eUICC triggers REFRESH operation following the enablement of
   a new profile.
3. Use "refresh register" to subscribe refresh indications (file
   path of EF_ICCID is used) in a similar way. This is used with
   older modems that do not support "refresh register all".

If ICCID change is detected, the already existing SIM hot swap
mechanism in MM is triggered.
