[mlir] update InferTypeOpInterface after c1eab57

The change in c1eab57 fixed the
behavior of `getDiscardableAttrDictionary` for ops that are not using
properties to only return discardable attributes. `InferTypeOpInterface`
was relying on the wrong behavior when constructing an adaptor and would
assume that all attributes were discardable, which is not the case.
