Inherit EventTarget interface instead of duplicating its code
Update most interfaces to stop using [EventTarget] IDL extended attribute
and inherit EventTarget instead. This avoids duplicating the EventTarget
API in each IDL and makes our IDL more standard.
Also remove [NoInterfaceObject] extended attribute from EventTarget to
facilitate testing and match the specification:
http://dom.spec.whatwg.org/#interface-eventtarget
Only 3 interfaces were not updated yet (Node, Window, Performance) because
they require special treatment at the moment.
