Allow using Alias column type for KafkaEngine
```
create table kafka
(
 a UInt32,
 a_str String Alias toString(a)
) engine = Kafka;

create table data
(
  a UInt32;
  a_str String
) engine = MergeTree
order by tuple();

create materialized view data_mv to data
(
  a UInt32,
  a_str String
) as
select a, a_str from kafka;
```
Alias type works as expected in comparison with MATERIALIZED/EPHEMERAL
or column with default expression.
