Reviewed by Timothy Hatcher.

This patch adds support for queuing and firing API events for web extensions.

Testing:
I added an event listener in the background page of a test extension, and with this code below,
I tested that the completion handler was successfully called.
EventListenerTypeSet set;
set.add(WebExtensionEventListenerType::ActionOnClicked);
fireEvents(set, makeBlockPtr([ protectedThis = Ref { *this }]() {
    RELEASE_LOG(Extensions, "KIARA");
}));

(WebKit::WebExtensionContext::queueStartupAndInstallEventsForExtensionIfNecessary):
Queue and fire event listeners.

(WebKit::WebExtensionContext::performTasksAfterBackgroundContentLoads):
(WebKit::WebExtensionContext::fireEvents):
Call the completion handler for persistent background pages. For non-persistent backgrounds, wake
up the background page and queue the listener to fire after the background is loaded.

(WebKit::WebExtensionContext::queueEventToFireAfterBackgroundContentLoads):
Add completion handler to queue of listeners to fires.

Add the extension context identifier. Without this, we won't know which context this message is for.
