What is the problem this feature will solve?

This sounds like a simple feature request. We already got EventTarget and Event. So my feature request is to have a globalThis.addEventListener. (along with remove & dispatch) added to the global scope (by extending EventTarget)

What is the feature you are proposing to solve the problem?

Deno, browser and web workers and even cloudflare workers already has a global event listener that can be used to listen to a variety of things.
It can be used for listening to eg PostMessage, network offline/online, background fetch, any kind of errors etc.

This is partly related to #43583
Having different code paths to solve the same things gets troublesome.

What alternatives have you considered?
