[mlir][NFC] Set `useFoldAPI` to `kEmitRawAttributesFolder` value for some dialects missed previously

[zero9178]

Summary

Found these while working on https://reviews.llvm.org/D141604. These were previously not found due to the old implementation only emitting warnings if an Op has a fold.

Changing these values both avoid the deprecation warning and if new folds were added to ops of these dialects, that they are already using the new API.
