SIM status page sync signal strength and service state behavior from systemUI

To make behavior consistent in the long run and refactor the code
into settingslib and call it from both Settings and SystemUI.

Bug: 110973964
Test: run testcase and do manual test - test case as below:
1. Testcase: packages/apps/Settings: -> ALL PASS
make RunSettingsRoboTests ROBOTEST_FILTER=SimStatusDialogControllerTest
2. Fake the service state's voice and data value,voice is out of service
and data is in-service,and then check service state and signal strength
at sim status page -> PASS
