RFR: JDK-8304959: Public API in javafx.css.Match should not return private API class PseudoClassState [v7]

Fri May 12 23:40:03 UTC 2023

> The class `PseudoClassState` is private API, but was exposed erroneously in the CSS API. Instead, `Set<PseudoClass>` should have been used. This PR corrects this.
