[EventAggregator] Log events for PER_DEVICE_COUNT_STATS reports

Adds a method to log CountEvents to the EventAggregator for reports
of type PER_DEVICE_COUNT_STATS. Updates the config update
method and the garbage collection method to handle the new type of
local aggregates.

Observation generation for PER_DEVICE_COUNT_STATS reports
will be added in a follow-up CL.
