Add geo-fencing for cellbroadcast

This add the ability to perform the geo-fencing check for cell broadcast
which has the warning area coordinates information. The cell broadcast
will not be broadcasted the UE's location is outside the polygon or
circle.

If the location is not available at the time when cell broadcast was
received, just broadcast the message regardless of the UE's location.
