Add Select() method to HTMLInputElement.

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.
