msc/USSD: add test cases with network-initiaded SS/USSD
This change introduces two new test cases for network-initiaded
USSD notification and network-initiaded USSD request, which are
based on the existing SS/USSD related test cases.
The idea of TC_lu_and_mt_ussd_notification is to verify that
a network-initiaded USSD notification can arrive subscriber in
IDLE mode using Paging procedure.
The idea of TC_lu_and_mt_ussd_during_mt_call is to verify that
a network-initiaded USSD notification can arrive subscriber in
DEDICATED mode (in this case during a call) on a separate
transaction.
