As a first step toward building clearer API distinction between computed and used styles, we should split out the data from RenderStyle into a new type, Style::ComputedStyle, and have RenderStyle contain and forward to it. This will be largely mechanical, but will allow follow ups where we convert RenderStyle (either keeping the name, or renaming it to Style::UsedStyle or Style::UsedStyleResolver or the like) to a readonly view-like type, which wraps a reference to Style::ComputedStyle.
