I didn't want to add another set of boilerplatey tree-walking methods, so here's a general-purpose one. :^) `for_each_effective_rule()` walks the tree of effective style rules, and runs the callback on each one, in either pre- or postorder. The previous `for_each_effective_style/keyframes_rule()` methods of `CSSStyleSheet` are then reimplemented in terms of `for_each_effective_rule()`, and we can get rid of their equivalents elsewhere.
