Review Comment:
I think `_2 = _3` may always be true. The problem with
`makeParquetFileAllTypes` is that every for each row, each column contains the
same integer value cast to the column's type, so it is not ideal for tests like
this. We can improve as part of
https://github.com/apache/datafusion-comet/issues/1269
