Lazily create LootContext for criterions

For each player on each tick, enter block triggers are invoked, and these create loot contexts that are promptly thrown away since the trigger doesn't pass the predicate

To avoid this, we now lazily create the LootContext if the criterion passes the predicate AND if any of the listener triggers require a loot context instance
