**Describe the bug**
Here's my table:
```sql
CREATE TABLE table2
(
        EventDate Date,
        Id Int32,
        Value Int32
)
Engine = MergeTree()
PARTITION BY toYYYYMM(EventDate)
ORDER BY Id;
```

Modify default value (intentionally wrong):
```
>>> alter table table2 modify column Value default 'some_string';

ALTER TABLE table2
    MODIFY COLUMN `Value` DEFAULT 'some_string'

Ok.

0 rows in set. Elapsed: 0.007 sec. 
```

Now you obviously cannot insert anything to this table, because:
```
>>> insert into table2 (EventDate, Id) values (1234567890, 2)

INSERT INTO table2 (EventDate, Id) VALUES

Received exception from server (version 20.9.3):
Code: 6. DB::Exception: Received from localhost:9000. DB::Exception: Cannot parse string 'some_string' as Int32: syntax error at begin of string. Note: there are toInt32OrZero and toInt32OrNull functions, which returns zero/NULL instead of throwing exception.. 

1 rows in set. Elapsed: 0.002 sec. 
```

**How to reproduce**
* Which ClickHouse server version to use: 20.9.3
* Which interface to use, if matters: I used standard CLI

**Expected behavior**
Currently ClickHouse doesn't check types compability while setting a DEFAULT value for a column. Maybe ClickHouse should validate DEFAULT values for type compability?

{
    if (type == ADD_COLUMN)
    {
        ColumnDescription column(column_name, data_type);
        if (default_expression)
        {
            column.default_desc.kind = default_kind;
            column.default_desc.expression = default_expression;
        }
        if (comment)
            column.comment = *comment;
        if (codec)
            column.codec = CompressionCodecFactory::instance().validateCodecAndGetPreprocessedAST(codec, data_type, false);
        column.ttl = ttl;
        metadata.columns.add(column, after_column, first);
        
        metadata.columns.flattenNested();
    }
    else if (type == DROP_COLUMN)
    {
        
        if (!clear && !partition)
            metadata.columns.remove(column_name);
    }
    else if (type == MODIFY_COLUMN)
    {
        metadata.columns.modify(column_name, after_column, first, [&](ColumnDescription & column)
        {
            if (to_remove == RemoveProperty::DEFAULT
