Add URL.createObjectURL and URL.revokeObjectURL

Hi, jsdom already supports the URL constructor, but not these 2 static methods, they are supported in most modern browsers.

@fredvollmer if using jest with jsdom and you want to noop this function you can add this code to setupTest.js (or an equivalent setup script)

function noOp () { }

if (typeof window.URL.createObjectURL === 'undefined') {
  Object.defineProperty(window.URL, 'createObjectURL', { value: noOp})
}
