LibWeb: Make box-shadow known throughout the CSS subsystem
This patch spreads box-shadows around: - The Values important to box-shadows are stored in a BoxShadowData struct - StyleProperties knows how to construct such a struct from a BoxShadowStyleValue and a Node knows how to ask for it - CalculatedValues contain BoxShadowData and expose them
