base: Do not allow MessagePumpObservers to consume events.

There is currently a single message-pump observer that can consume an event,
and it does so only when the num-lock key is pressed on Chrome OS. But it
doesn't need to consume the event, because no other dispatcher/observer cares
about this event. So remove a MessagePumpObserver's ability to consume an
event. This makes the code cleaner, and easier to understand.
