LibWeb: Create HTMLInputElement UA shadow tree when inserted into DOM

Browse Source 
Previously, we were creating a user-agent shadow tree when constructing
a layout tree. This meant that we did DOM manipulation (and consequently
style invalidation) during layout tree construction, which made things
very hard to reason about in Layout::TreeBuilder.

Simply everything by simply creating the UA shadow tree when the input
element inserted into a parent node instead.
