quectel: Check SIM swap after "+QUSIM: 1" URC

Browse Source 
Quectel emits "+QUSIM: 1" after eUICC reinitialization. Detect it
and perform SIM swap check if one is encountered.

The motivation here is that M2M eUICC profile switch causes eUICC
reset and this is one way to detect and handle profile switches
properly on Quectel modems. The existing SIM hot swap mechanism is
used as it appears to be suitable for handling profile switches as
well as physical swapping of SIM cards.

/* "+QUSIM: 1" URC is emitted by Quectel modems after the USIM has been
* (re)initialized. We register a handler for this URC and perform a check
* for SIM swap when it is encountered. The motivation for this is to detect
* M2M eUICC profile switches. According to SGP.02 chapter 3.2.1, the eUICC
* shall trigger a REFRESH operation with eUICC reset when a new profile is
* enabled. The +QUSIM URC appears after the eUICC has restarted and can act
* as a trigger for profile switch check. This should basically be handled
* the same as a physical SIM swap, so the existing SIM hot swap mechanism
* is used.
