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