**Describe the bug**
`CODEC` is allowed for `ALIAS` column

**How to reproduce**
``` sql
CREATE TABLE t102
(
    `c0` ALIAS c1 CODEC(ZSTD),
    `c1` String
)
ENGINE = Memory()

Ok.

DESCRIBE TABLE t102

┌─name─┬─type───┬─default_type─┬─default_expression─┬─comment─┬─codec_expression─┬─ttl_expression─┐
│ c0   │ String │ ALIAS        │ c1                 │         │ ZSTD(1)          │                │
│ c1   │ String │              │                    │         │                  │                │
└──────┴────────┴──────────────┴────────────────────┴─────────┴──────────────────┴────────────────┘

```
**Expected behavior**
Error
{
    if (type == MODIFY_TTL)
        return true;
    if (!ttl || type != MODIFY_COLUMN)
        return false;
    bool ttl_changed = true;
    for (const auto & [name, ttl_ast] : metadata.columns.getColumnTTLs())
    {
        if (name == column_name && queryToString(*ttl) == queryToString(*ttl_ast))
        {
            ttl_changed = false;
            break;
        }
    }
    return ttl_changed;
}
