LibWeb: Make CSSStyleDeclaration an abstract class

Browse source 
This patch moves the CSS property+value storage down to a new subclass
of CSSStyleDeclaration called PropertyOwningCSSStyleDeclaration.

The JavaScript wrapper for CSSStyleDeclaration now calls virtual
functions on the C++ object.

This is preparation for supporting computed style CSSStyleDeclaration
objects which won't have internal property storage, but rather an
internal element pointer. :^)
