Previously, we registered `@property` rules during parsing, and treated them the same as `CSS.registerProperty()` calls. This is not correct for a couple of reasons: One, the spec wants us to distinguish between those two sources of registered custom properties, with `CSS.registerProperty()` calls taking precedence. Two, we never removed the registered property when its `@property` was removed from the document. This commit deals with this by iterating active CSSPropertyRules to find which ones currently apply, and storing those in a cache. This cache is invalidated whenever the Document's style is invalidated, which happens whenever a CSSRule is added or removed from the Document. The attached test demonstrates this now working as it should.
