Table discovery allows unsupported Federated structure

      Description

      --source suite/federated/have_federatedx.inc
       
      create table t (a int, b int as (a));
      --eval create table tf connection 'mysql://root@127.0.0.1:$MASTER_MYPORT/test/t' engine=Federated
       
      show create table tf;
       
      # Cleanup
      drop table tf, t;
      

      In the test case above, the table is created without errors or warnings, but then any action on this table fails with ER_UNSUPPORTED_ENGINE_FOR_GENERATED_COLUMNS:

      10.3 730eb1c4

      mysqltest: At line 6: query 'show create table tf' failed: 1910: FEDERATED storage engine does not support generated columns
      

      The unpleasant (and possibly realistic) side-effect is that such tables break mysqldump and some queries from INFORMATION_SCHEMA.
