LibWeb/CSS: Move property code from CSSStyleDeclaration to *Properties

CSSStyleDeclaration is a base class that's used by various collections
of style properties or descriptors. This commit moves all
style-property-related code into CSSStyleProperties, where it belongs.

As noted in the previous commit, we also apply the CSSStyleProperties
prototype now.
