Document.cpp still handled CSS fallout from stylesheet media query match changes directly. Move active stylesheet evaluation, rule-cache invalidation, shadow-root fallout, and slot propagation into the CSS invalidation helper. Document continues to decide when media queries should be evaluated. The helper now owns the style invalidation consequences when stylesheet media queries change match state.
