Refactor client previews_state logic out of dispatcher into component

This change adds support for setting the new NoScript client preview bit
in content::PreviewsState and in the process makes some refactors to
clear up deceptive naming (GetPreviewsState => DeterminePreviewsState)
and moves some logic out of dispatcher and into a new previews component
utility method.
