[bookmarks] Add folder selection logic to BookmarkQueryHandler

- Add folder picker parent selection into BookmarkQueryHandler classes.
- Add new argument to #getTopLevelFolderIds which determines if the
  visible while empty logic is used. This is to support selecting a
  folder, which needs to include even the empty top-level folders.
- Slight adjustments to FakeBookmarkModel w/ tests.
