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.

bf312c2a5b Fix ALTER DROP COLUMN of nested column with compact parts 
ALTER DROP COLUMN of nested column did not requires mutation before, and
so it leaves nested column as-is, and in case of compact parts
subsequent alter, that requires mutation, will trigger READ_COLUMN of
that nested column (because it exists in part), but it will fail because
there is no such column in the table already.

Here is example of such a failure on CI - [1].
