HwmonTempSensor: Fix a crash when an I3C device is scanned

When an I3C device is registered in hwmon sub-system, the device would have
a long address tag such as '0-4cc31020000', so if the scanning loop uses
'stoi' for the address parsing, this service crashs by this error.

    terminate called after throwing an instance of 'std::out_of_range'
      what():  stoi
    Aborted (core dumped)

To prevent this issue, this commit replaces 'stoi' with std::from_chars
to uint64_t type since BasicVariantType can be up to uint64_t and it
actually parses unsigned numbers from Bus and Address settings.

Tested: HwmonTempSensor service didn't crash even when an I3C device is
enumerated in sysfs.
