transformations: Enable dmp.swap stencil bufferization.

[PapyChacal]

• Implement side effect interface of dmp.swap
• Slightly extend the side-effect analysis of stencil bufferization.
• Add a dmp.swap bufferization pattern in stencil-bufferize. To just work for now as dmp is only used in stencil so far - decoupling this as shape inference and all is left to future work!
