Aart Bik 8154494e28 [mlir][sparse] refactor sparsification and bufferization pass into proper TD pass
Registering the SparsificationAndBufferization into a proper TD pass
has the advantage that it can be invoked and tested in isolation. This
change also moves some bufferization specific set up from the pipeline
file into the pass file, keeping the logic more locally.
