[NTP Client][Reland]Use the separate button style for the NoArticles status

Original issue's description:
> [NTP Client] Use the separate button style for the NoArticles status
>
> Makes the articles and bookmarks sections use the same style of status
> card when they have no snippets.
>
> the hasMoreButton property of categories now only determines whether
> the action item will be shown when there are suggestions to display.
>
> This patch also lets the SuggestionsCategoryInfo be aware of the
> current category it is describing, and moves various category specific
> behaviours into the SuggestionsCategoryInfo class.
>
