  [mlir][Tensor] Fold destination-style ops into `tensor.unpack` operation. (#71468)

The destination operand of the `tensor.unpack` operation is only needed
to carry shape information. So if the producer of the destination
operand implements the `DestinationStyleOpInterface`, then fold it into
the `tensor.unpack` operation by replacing the destination operand with
the destination for the source.
