Tame GTM & 3p scripts to improve INP

Add this to before you load any 3p (especially GTM) in the document.

What it does is when it executes:

for click, auxclick, mousedown, keyup and submit, installs a document level addEventListener override that intercepts added listeners if it's likely they from from a 3p (-> based on the 3rd argument passed to the fn)

On the document load event (so that it executes after GTM etc.):

	/**
	* Queue of functions to invoke
	* @type {Array<(time: number) => void>}
	*/
	let callbacks = [];

	let channel = new MessageChannel();

	let postMessage = (function() {
	this.postMessage(undefined);

	/**
	* DevTools snippet – find potential stutter sources
	* Run in the Chrome DevTools console on any page
	* Flags:
	* 1. Elements > 1000×1000 px that have any transform-* or opacity set
	* 2. Elements that have any filter applied
	* If at least one of each category exists → we have a match.
	* Matching elements get a red 3 px outline and a console table.
