**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 (size_t i = 0; i < block.columns(); ++i)
    {
        auto & column = block.getByPosition(i);
        if (!column.column) 
            column.column = column.type->createColumn();
    }
}
void joinTotals(Block left_totals, Block right_totals, const TableJoin & table_join, Block & out_block)
{
    if (table_join.forceNullableLeft())
        JoinCommon::convertColumnsToNullable(left_totals);
    if (table_join.forceNullableRight())
        JoinCommon::convertColumnsToNullable(right_totals);
    for (auto & col : out_block)
    {
        if (const auto * left_col = left_totals.findByName(col.name))
            col = *left_col;
        else if (const auto * right_col = right_totals.findByName(col.name))
            col = *right_col;
        else
            col.column = col.type->createColumnConstWithDefaultValue(1)->convertToFullColumnIfConst();
        
        if (col.column->size() != 1)
            col.column = col.column->cloneResized(1);
    }
