We previously had PropertyOwningCSSStyleDeclaration and ResolvedCSSStyleDeclaration, representing the current style properties and resolved style respectively. Both of these were the CSSStyleDeclaration type in the CSSOM. (We also had ElementInlineCSSStyleDeclaration but I removed that in a previous commit.) In the meantime, the spec has changed so that these should now be a new CSSStyleProperties type in the CSSOM. Also, we need to subclass CSSStyleDeclaration for things like CSSFontFaceRule's list of descriptors, which means it wouldn't hold style properties. So, this commit does the fairly messy work of combining these two types into a new CSSStyleProperties class. A lot of what previously was done as separate methods in the two classes, now follows the spec steps of "if the readonly flag is set, do X" instead, which is hopefully easier to follow too. There is still some functionality in CSSStyleDeclaration that belongs in CSSStyleProperties, but I'll do that next. To avoid a huge diff for "CSSStyleDeclaration-all-supported-properties-and-default-values.txt" both here and in the following commit, we don't apply the (currently empty) CSSStyleProperties prototype yet.
