Update PhoneConfigurationManager to support SimultaneousCallingRestrictionsTest.

This CL makes minor updates to PhoneConfigurationmanager in order to support
the implementation of SCRT:
1) Fixes a bug a PhoneConfigurationManagerTest and SimultaneeousCallingTrackerTest
where we were sending an int[] instead of an ArrayList for the enabledLogicalSlots.
2) Fixes a bug where the PhoneCapability was not being updated properly when the
modem moves from unavailable -> available, which would cause CTS flakiness. We
now re-requery the modem once when the modem moves to available state.

Test: atest SimultaneousCallingRestrictionsTest
Bug: 328293858
