Add Emergency Call Routing in HAL

Some countries or carriers require some emergency numbers that must
be handled with normal call routing or emergency routing.

In multi-sim senario, this radio request will be sent through the IRadio
service that serves the subscription the emergency number belongs to,
no matter of the PUK/PIN state of the subscription and the service state.
