Reviewed by Timothy Hatcher.

This patch allows WebFrameLoaderClient to tell web extensions code about the various stages of frame loading.

The flow is:
- WebFrameLoaderClient sends a message to the WebExtensionController using IPC.
- WebExtensionController iterates over all the WebExtensionContexts and:
        - Sends a message to their WebExtensionContextProxy using IPC.

WebFrameLoaderClient::dispatchDidCommitLoad -> onCommitted and onDOMContentLoaded
WebFrameLoaderClient::dispatchDidFinishLoad -> onCompleted
WebFrameLoaderClient::dispatchDidFailLoad -> onErrorOccurred

And then the WebExtensionContextProxy will fire the event on the extension pages that listen to it.
