Draft: Add Quectel MBIM command to read firmware info

Ivan Mikhanchuk requested to merge ivan.mikhanchuk/ModemManager:quectel-mbim-firmware-info into main

Quectel MBIM modems report only the major part of the firmware version in the MBIM device caps:

[/dev/cdc-wdm0] Device capabilities retrieved:
              Device type: 'embedded'
           Cellular class: 'gsm'
...
            Firmware info: 'EM05GFAR07A05M1G'
            Hardware info: 'QUECTEL Mobile Broadband Modul'

This MR adds custom Quectel MBIM command to read the full version info:
