Remove dependency on //chrome from bookmark_undo_utils

Remove dependency on //chrome from bookmark_undo_utils

Change ScopedSuspendBookmarkUndo to take the BookmarkUndoService
instead of the Profile in its constructor and change client code
accordingly.

Add a GetProfileIfExists() method to BookmarkUndoServiceFactory
to avoid service creation when suspending the undo/redo mechanism
as if the service is initialized at BookmarkModel creation time.
