Support AbortSignal in addEventListenerOptions to unsubscribe from events:

Blink already added support for this.

Source/WTF:
Add initializeWeakPtrFactory() protection function to CanMakeWeakPtr so that a subclass
can eagerly initialize the WeakPtrFactory even if it does not subclass
WeakPtrFactory<T, WeakPtrFactoryInitialization::Eager>. MessagePort used to subclass
WeakPtrFactory<T, WeakPtrFactoryInitialization::Eager> for thread-safety reason but it
now subclasses WeakPtrFactory<T, WeakPtrFactoryInitialization::Lazy> via EventTarget.
