Reviewed by Tim Nguyen.

On an <input type=checked>, the presence of the checked="" attribute
determines whether :default matches. We must invalidate :default when
the attribute is added or removed on a checkable input element.

We also must invalidate :default when the type="" changes. Just use
AnyValue rather than compute ahead of time what the new pseudo-class
match value will be, in HTMLInputElement::updateType.
