Make OfflinePage ContentSuggestions dismissable

Make MakeUniqueID and friends const methods.
Add a new pref to store the IDs of all dismissed offline pages. Add
methods in OfflinePageSuggestionsProvider to store and load these IDs.
Modify OnOfflinePagesLoaded to only forward non-dismissed items.
Implement ClearDismissedSuggestionsForDebugging and a temporary version
for GetDismissedSuggestionsForDebugging (the Snippets Internals will
need refactoring for this to work properly).
