[EventDispatcher] Add CompiledEventDispatcher

The listener graph is settled when the container is compiled, but it reaches
the dispatcher as work: one addListener() call per listener, each building a
closure that then hides which service the listener is.

CompiledEventDispatcher takes the same graph as data, the id and the method
of each listener in the order they must run in, plus the locator to fetch
them from. CompileListenersPass writes that map from the addListener() calls
at TYPE_AFTER_REMOVING, so the passes reading those calls still find them,
and a decorated dispatcher keeps the calls it forwards.

A listener is still fetched only when it is about to run, and anything but
dispatching moves the map back into a plain EventDispatcher.
