LibWeb: Add LayoutStyle, a place to store style info for layout & paint

Browse source 
StyleProperties is really only the specified "input" to what eventually
becomes the used/computed style we use for layout and painting.

Unlike StyleProperties, LayoutStyle will have strongly typed values for
everything it contains (i.e no CSS::ValueID or strings, etc.)

This first patch moves z-index into LayoutStyle.
