Add ContentSuggestionsCategoryFactory; Store categories as ints

Replace the ContentSuggestionsCategory enum with a thin wrapper class
around an int to allow for categories to be added dynamically at
runtime. Add a ContentSuggestionsCategoryFactory, which creates
instances and keeps track of the ordering of the categories.

Adjust the ContentSuggestionsService to use the category ordering
provided by the new factory. Adjust ContentSuggestionsProvider to use
the factory for recovering categories from combined IDs and move the
provided_categories_ field to subclasses. Adjust the SnippetsBridge
to use the new factory.

Make ContentSuggestionsService recognize new/removed categories

Change the OnNewSuggestions and OnCategoryStatusChanged methods in
ContentSuggestionsService so that they recognize new categories being
added and OnCategoryStatusChanged recognizes categories being removed
when their status changes to NOT_PROVIDED. This allows providers to
change their provided categories dynamically.

Little fix: Make Category(int) constructor explicit

Add CategoryInfo for meta information of content suggestions Categories

Apart from the ContentSuggestions in a Category and its current status,
there is meta information assigned with a Category that does not change
even for dynamically added categories. This information includes the
title, for example.

Implement a new CategoryInfo struct (with currently only the title
and a card_layout field) and corresponding methods to hand the
information from the ContentSuggestionsProviders to the
ContentSuggestionsService and out towards the UI.
Implement those methods in the three providers we currently have.

For the offline pages, only use a placeholder string at the moment,
because it will provide two distinct categories with different titles
in the future.
