   @snuyanzin My rough idea is like:
   * Pass `resolvedPredicates` and `pushdownParams` to 
`JdbcRowDataLookupFunction`
   * `FieldNamedPreparedStatement` may be need to adapt to allow pass 
additional predicates
   *  set params to additional predicates somewhere, maybe after 
`lookupKeyRowConverter.toExternal`
   
   My goal is to keep current `ParameterizedPredicate` and 
`JdbcFilterPushdownPreparedStatementVisitor` unchanged, and adapt 
`JdbcRowDataLookupFunction` just like how we did for `JdbcRowDataInputFormat`. 
The challenge is how to make it work with `FieldNamedPreparedStatement` now.
