LibWeb/HTML: Use default input size (20) when value is 0

Browse Source 
According to the HTML specification, the `size` attribute of an input
element must be a valid non-negative integer greater than zero. If the
value is invalid or set to `0`, the default size of `20` should be used.

This small change fixes one issue identified in
https://wpt.live/html/rendering/widgets/input-text-size.html
The WPT test suite was also automatically imported.
