Update params/columns data_types for prepare packet

[Zhaars]

During conversation with @Lagovas about #517 . We faced that we didnt change data_types for intermediate params/columns ColumnDefinition that are following after COM_STMT_PREPARE_OK packet. It wasnt noticed at previous PR because all driver ignore it and use only last metadata field from STMT_EXECUTE packet. But we do have to change it because some ORM might use these intermediate packet to make some cachin on its own side.
