feat: [#1468] Add AbortSignal.any() static method

[ezzatron]

This PR adds the AbortSignal.any() static method.

This method is extremely useful for combining multiple signals together. An example would be adding a timeout to a manually aborted signal:

const timeout = AbortSignal.timeout(10000);
const controller = new AbortController();

const signal = AbortSignal.any([timeout, controller.signal]);

// Will abort after 10 seconds, or when controller.abort() is called
await fetch("https://example.org/, { signal });
