[mlir][tensor][linalg] Introduce DataLayoutPropagation pass.

It introduces a pattern that swaps `linalg.generic + tensor.pack` to
`tensor.pack + linalg.generic`. It requires all the iteration types
being parallel; the indexing map of output operand is identiy. They can
all be relaxed in the future.

The user can decide whether the propagation should be applied or not by
passing a control function.
