Handle preferred SIM for ACTION_CALL

Previously preferred SIM is handled only by precall, which covers dialing with dialer or with the special receiver contacts uses. If a third party app uses ACTION_CALL or telecomManager.placeCall(), then the in call UI will be launched directly and the old account selection dialog will be used without preferred SIM support.

In this CL logic from CallingAccountSelector is refactored out so InCallActivity can use it for the dialog.

Bug: 73718976
Test: Unit tests, In call UI not covered.
