Adds Phone Capability check to E911 slot selection

Adds an additional step to the process of selecting which slot to use to
place an emergency call. The slots are now sorted by the number of
available Radio Access family Capabilities and if there are no SIMs in
service, the slot with the highest capabilities is chosen.
