**Describe the bug**
Table creation with named tuples is broken

**How to reproduce**
ClickHouse server version 20.5.3.27

```
:) SELECT version();

┌─version()─┐
│ 20.5.3.27 │
└───────────┘
```
```
:) CREATE TABLE test.tuple
(
    `j` Tuple( a Int8, b String)
)
ENGINE = Memory;


Received exception from server (version 20.5.3):
Code: 62. DB::Exception: Received from localhost:9000. DB::Exception: Syntax error (data type): failed at position 9: Int8, b String). Expected one of: LIKE, GLOBAL NOT IN, AS, IS, OR, QuestionMark, BETWEEN, NOT LIKE, AND, Comma, alias, IN, Dot, NOT, Arrow, token, NOT IN, GLOBAL IN.
```
```
:) CREATE TABLE test.tuple_from_select
ENGINE = Memory AS
SELECT CAST((1, 'Test'), 'Tuple( a Int8,  b String)') AS j;


Received exception from server (version 20.5.3):

```

**This works fine on 20.4.6.53:**
```
:) SELECT version();

┌─version()─┐
│ 20.4.6.53 │
└───────────┘
```
```
:) CREATE TABLE test.tuple
(
    `j` Tuple( a Int8, b String)
)
ENGINE = Memory;

Ok.
```
```
:) SHOW CREATE TABLE test.tuple

┌─statement───────────────────────────────────────────────────────────────────────┐
│ CREATE TABLE test.tuple
(
    `j` Tuple(
    a Int8, 
    b String)
)
ENGINE = Memory │
└─────────────────────────────────────────────────────────────────────────────────┘
```
```
:) CREATE TABLE test.tuple_from_select
ENGINE = Memory AS
SELECT CAST((1, 'Test'), 'Tuple( a Int8,  b String)') AS j;

Ok.
```

        if (create.temporary)
            required_access.emplace_back(AccessType::CREATE_TEMPORARY_TABLE);

        }
    }
    else

            required_access.emplace_back(AccessType::CREATE_TEMPORARY_TABLE);
        else

    }
    if (create.to_table_id)
        required_access.emplace_back(AccessType::SELECT | AccessType::INSERT, create.to_table_id.database_name, create.to_table_id.table_name);
    if (create.storage && create.storage->engine)
