<https://webkit.org/b/119903> Make Settings ref-counted (and let Frame keep a ref!)

Reviewed by Geoff Garen.

Let Frame hold a RefPtr<Settings> so Frame::settings() isn't forced to go through Page.
It now also returns a reference, as it can never be null.

Removed 8.8 million lines of null-checking as a result.
