[cobalt][LocalAggregation] Remove direct store access from
AddNumericEvent()

- adds a function to aggregation_utils to handle the logic of updating
a known aggregate. This function will later be used by
GenerateObservations as well.
- currently the EventAggregation directly locks and and modifies the
AggregateStore's internal state. This CL moves the responsibility of
locking and setting the correct state of the store to the Aggregate Store.
- for more information see go/cobalt-local-aggregation-redesign
