Query like `select * from ut_p partitions(p2) where cast(var['a'] as int) > 0` will fall through parition/tablet prunning since it's plan like
```
mysql> explain analyzed plan select * from ut_p where id = 3 and cast(var['a'] as int) = 789;

with an extra LogicalProject on top of LogicalOlapScan, so we should handle such case to prune parition/tablet

1. variant type core dump at call get_data_at function, as not impl this function.
2. some case can't pass at old planner and fold_constant_by_be = on.
3. open enable_fold_constant_by_be = true.
if some odbc tables use the same resource, and restore not all odbc tables, it will not retain the resource.
and check some conf for backup/restore
