DO NOT MERGE CarrierIdentifier listen for simrecordsOverride event

CarrierTestOverride is a test API to override sim records
information. It notify the listeners that new sim records is available.
For example, DcTracker will refetch and APN settings and sent out an
initial attach request to RIL. It turns out that frequent
carrierTestOverride could end up with frequent RIL requests and
eventually crash the RILD. The short term fix is notify sim records
override events without waking update other components.
The long term fix is ganrantee RIL do not crash and also try to
decouple DcTracker and other components from listening internal
sim records loaded events.
