Support HTMLElement#inert property

[mbehzad]

Hi,
according to the HTML Spec (https://html.spec.whatwg.org/multipage/interaction.html#dom-inert) the HTMLElement has the inert property which reflects its inert boolean attribute and the inert state of the DOM element (https://html.spec.whatwg.org/multipage/interaction.html#inert) (no focus, click, etc).

happy-dom seems not yet to support this. e.g.

import { Window } from 'happy-dom';

const window = new Window();
const document = window.document;
document.body.innerHTML = '<div class="container"></div>';
const container = document.querySelector('.container');

container.inert = true;

console.log(container.outerHTML); // will print `<div class="container"></div>` instead of `<div class="container" inert></div>`

cheers
