Support TextEncoder & TextDecoder

[Ayc0]

Is your feature request related to a problem? Please describe.

On the global scope, TextEncoder & TextDecoder are available (see MDN).

But when I run this code:

const h = require('happy-dom');
const w = new h.Window();
w.TextEncoder // undefined

This poses an issue for tests running in Jest with @happy-dom/jest-environment, testing code using TextEncoder

Describe the solution you'd like
