Add Select() method to HTMLInputElement.

[dmitshur]

• According to https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement, it has that method, just like https://developer.mozilla.org/en-US/docs/Web/API/HTMLTextAreaElement does (which this package already supports).
• Note that HTMLInputElement and HTMLTextAreaElement share many other common methods like CheckValidity, SetCustomValidity, SetSelectionRange, but this package only supports the latter.
• Tested and it works in latest stable Chrome.
