MutationRecord should be globally available

[wojtekmaj]

Describe the bug

MutationRecord should be globally available, as it is in the browser.

To Reproduce

I have a test in my test suite that checks if MutationObserver callback gets called with an array of MutationRecord. Because it's not globally available, this test code:

    expect(listener).toHaveBeenCalledWith(
      [expect.any(MutationRecord)],
      expect.any(MutationObserver),
    );

is, in reality,

    expect(listener).toHaveBeenCalledWith(
      [expect.any(undefined)],
      expect.any(MutationObserver),
    );

and results in an error:

TypeError: any() expects to be passed a constructor function. Please pass one or use anything() to match any object.

As a temporary workaround, I can to import it manually into my module:

import MutationRecord from 'happy-dom/lib/mutation-observer/MutationRecord.js';

and it works just fine.

Expected behavior

MutationRecord to be globally available.
