/// Efficient way of iterating through the register tiles at a particular position which
/// also is safe against modifications made to the list of tiles while the action is running.
/// The limitation compared to Get<> is it can only get RegisterTiles, but the benefit is it avoids
/// GetComponent so there's no GC. The OTHER benefit is that normally iterating through these
/// would throw an exception if the RegisterTiles at this position were modified, such as
/// being destroyed are created within the specified action. This method uses a locking mechanism to avoid
/// such issues - it's safe to add / remove register tiles.
