[Refactoring] Implement RuleCollector
https://bugs.webkit.org/show_bug.cgi?id=109916

Reviewed by Antti Koivisto.

Implemented rule collector for an element and collector for a page.
Not all members in class State are required entire while resolving
a style.

No new tests, because just refactoring.
