CPT: build carrier privileges cache when AccessRules are loaded

This change builds carrier privileges cache immediately when
knows UiccAccessRule in the profile has been loaded.

Previously CarrierPrivilegesTracker builds the CP cache only
when received SIM_STATE_LOADED. This removes the dependency
from CPT to UiccProfile but brings a tiny delay for clients
like SUW which needs to get carrier packages in the first
place.
