perf tools: Add event_update user level event
It'll serve as a base event for additional event attributes details, that are not part of the attr event. At the moment this event is just a dummy one without any specific functionality. The type value will distinguish the update event details. It'll come in the following patches. The idea for this event is to be extensible for any update that the event might need in the future.
