Add a new interface `FindPayloadReplacementOpInterface` to specify ops that should be skipped when looking for payload replacement ops. Such ops are typically metadata-only ops.
With this change, we no longer need to maintain a custom TrackingListener in the tensor dialect.
Note: `CastOpInterface` by itself is not sufficient. Some metadata-only ops such as "tensor.reshape" are not casts, and it would be incorrect for them to implement the `CastOpInterface`.
