Interface method implementation cannot be overridden by the user. In the interface implementation you have to make a choice whether to convert a tensor type to a memref with identity layout or fully dynamic layout map. We want users to be able to customize behavior, therefore, there must be some kind of hook in the `BufferizationOptions`.
