Review Comment:
Maybe we can enhance `eliminate_filter` optimizer rule to eliminate the
filters(in where clause) that always not be true and replace by a
`EmptyRelation`.
like we do for `where false` in
https://github.com/apache/arrow-datafusion/blob/8284371cb5dbeb5d0b1d50c420affb9be86b1599/datafusion/optimizer/src/eliminate_filter.rs#L55-L62
