gsm: add new property to track which facility locks are enabled

The property EnabledFacilityLocks on the .Modem.Gsm.Card interface
is a bit mask that indicates which of the various personalization
codes from 3GPP TS 22.022, plus the SIM PIN lock and SIM PIN2 lock,
are enabled. The set of facility locks supported by the modem is
determined at the time the modem is initialized, and the state of
each supported lock (enabled or disabled) is determined. When the
state of a lock changes, a property-change signal is sent out. Note
that ModemManager only supports enabling and disabling SIM-PIN, via
the EnablePin method on Modem.Gsm.Card.
