Resource logging when using AbortController signal

[Cody Brouwers]

I've enabled setResourceLoggingEnabled and it works great until I add an AbortController signal to my fetch calls. I did some digging and it seems that when using a signal the overwritten onreadystatechange property doesn't get called in the resource-logger.ts here.

I was able to get it working If I use instead invoke that same function with a listener like this:

super.addEventListener("readystatechange", () => {

I'm not too familiar with the internals of XMLHttpRequest and how fetch uses it so I'm not sure why this fixes the issue but if you think this is a safe change to make I'm happy to open a PR!
