[Refactoring] Make m_state an on-stack object
https://bugs.webkit.org/show_bug.cgi?id=109909

Reviewed by Antti Koivisto.

Mode m_state, an instance of StyleResolver::State, an on-stack object.
The state is only required in styleForElement, styleForKeyframe and
so on. No need to keep the state outside of those methods.

No new tests, because just refactoring.
