**Usage**
Postgres, MySQL, and Oracle support the expression `LEFT JOIN ... ON 1 = 1`, but ClickHouse does not.

It may be possible to replace `LEFT JOIN ... ON 1 = 1` with `CROSS JOIN`, but I want to use the query in the same form for lots of databases.

Please support the expression `LEFT JOIN ... ON 1 = 1`.


**Detailed SQL**
```SQL
CREATE TABLE test
(
    `name` Nullable(String),
    `id` int
)
ENGINE = Log();

insert into test values ('a', 1) ('b', 2) (null, 3);

select * from test t1 left join (select * from test ) t2 on 1 = 1   
-- DB::Exception: Not equi-join ON expression: 1 = 1. No columns in one of equality side.: While processing 1 = 1.
```

{
    for (auto & [pos, added] : right_nullability_changes)
    {
        auto & col = block.getByPosition(pos);
        if (added)
            JoinCommon::convertColumnToNullable(col);
        else
            JoinCommon::removeColumnNullability(col);
    }
    for (auto & [pos, added] : right_lowcard_changes)
    {
        auto & col = block.getByPosition(pos);
        if (added)
        {
            if (!col.type->lowCardinality())
                col.type = std::make_shared<DataTypeLowCardinality>(col.type);
            col.column = changeLowCardinality(col.column, col.type->createColumn());
        }
        else
        {
            col.column = recursiveRemoveLowCardinality(col.column);
            col.type = recursiveRemoveLowCardinality(col.type);
        }
    }
}
