LibWeb: Add ComputedCSSSstyleDeclaration and support 2 properties :^)
getComputedStyle(element) now returns a ComputedCSSStyleDeclaration object, which is a live view of the computed style of a given element. This works by ComputedCSSStyleDeclaration being a wrapper around an element pointer. When you ask it for a CSS property, it gets the latest computed style values from the element and returns them as a CSS::StyleProperty object. This first cut adds support for computed 'color' and 'display'. In case the element doesn't have a corresponding node in the layout tree, we fall back to using specified style instead. This is achieved by performing an on-the-fly style resolution for the individual element and then grabbing the requested property from that resolved style.
