This commit migrates all bookmarks to be polymorphic (using the bookmarkable_id and bookmarkable_type) columns. It also deletes all the old code guarded behind the use_polymorphic_bookmarks setting and changes that setting to true for all sites and by default for the sake of plugins. No data is deleted in the migrations, the old post_id and for_topic columns for bookmarks will be dropped later on.
