[proposal] add hooks support to all dom helpers + settled and wait-until

[runspired]

Some such as waitFor do not implement the hooks.

Some which do implement hooks (such as click) could still benefit from additional hooks wrapping of sub-helpers like focus and mouse-down etc.

My use-case is pretty simple, I'm doing this:

import { _registerHook } from '@ember/test-helpers';

const SHOW_SPANS = true;

if (SHOW_SPANS) {
	let SPAN = 0;
	['select', 'click', 'focus', 'fillIn', 'blur', 'waitFor', 'waitUntil', 'scrollTo', 'settled', 'visit'].forEach(
		(helper) => {
			let spanId;
			_registerHook(helper, 'start', function () {
				spanId = SPAN++;
				performance.mark(`${helper}-${spanId}-start`);
			});
			_registerHook(helper, 'end', function () {
				performance.mark(`${helper}-${spanId}-end`);
				performance.measure(`${helper}-${spanId}`, `${helper}-${spanId}-start`, `${helper}-${spanId}-end`);
			});
		},
	);
}
