Detect sim absent in EmergencyNumberTracker in multi-sim case

Legacy implementation of {@link PhoneNumberUtils#isEmergencyNumberInternal}
  was applying sim-absent emergency numbers
 ("112,911,000,08,110,118,119,999") in 3gpp in multisim case if one of
 the sims is absent and one of the sims is active. However, in multi-sim
 case such as DSDS, if one of sims is active, UE shall not apply
 sim-absent emergency numbers.

In multi-sim mode, as long as there is one sim active, the device
 is not in sim-absent mode.
