  Log Message:
  -----------
  [mlir][linalg] Introduce a separate EraseIdentityCopyOp Pattern.

Split out an EraseIdentityCopyOp from the existing RemoveIdentityLinalgOps pattern. Introduce an additional check to ensure the pattern checks the permutation maps match. This is a preparation step to specialize RemoveIdentityLinalgOps to GenericOp only.
