Migrate the SingleCategoryPreferences and ChosenObjectPreferences from
deprecated Framework preferences to Support Library preferences.

This change also removes the complete fragment layout override used by
Storage preferences in favor of simply appending the custom views to the
bottom of the layout.

Because this is the first fragment migrated which contains a
ChromeImageViewPreference, it includes some duplication of code so that
the compat and non-compat image view preferences can coexist. Once the
remaining ChromeImageViewPreferences are migrated to support library,
this duplicate code will be removed (https://crbug.com/967022).
