Make NGRAN have the lowest priority in NO SIM state
Today if the last valid subscription supports NGRAN for emergency calls,
NGRAN has higher preference than 3G or 2G when the SIM is removed
in AP domain selection.
Since full NR scanning takes more time, before user ends the call,
it's hard for modem to complete network scan in 2G only coverage.
To make AP domain selection behavior as CP domain selection,
make NR have the lowest priority when SIM removed as other carriers.
