**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.
```

const auto & onexprs = table_join->getClauses();
        for (size_t onexpr_idx = 0; onexpr_idx < onexprs.size(); ++onexpr_idx)
        {
            ColumnRawPtrs key_columns;
            for (const auto & name : onexprs[onexpr_idx].key_names_right)
                key_columns.push_back(all_key_columns[name]);
            
            ConstNullMapPtr null_map{};
            ColumnPtr null_map_holder = extractNestedColumnsAndNullMap(key_columns, null_map);
            
            UInt8 save_nullmap = 0;
            if (isRightOrFull(kind) && null_map)
            {
                
                for (size_t i = 0; !save_nullmap && i < null_map->size(); ++i)
                    save_nullmap |= (*null_map)[i];
            }
            auto join_mask_col = JoinCommon::getColumnAsMask(block, onexprs[onexpr_idx].condColumnNames().second);
            
            ColumnUInt8::MutablePtr not_joined_map = nullptr;
            if (!multiple_disjuncts && isRightOrFull(kind) && !join_mask_col.isConstant())
            {
                const auto & join_mask = join_mask_col.getData();
                
                not_joined_map = ColumnUInt8::create(block.rows(), 0);
                for (size_t i = 0, sz = join_mask->size(); i < sz; ++i)
                {
                    
                    if ((*join_mask)[i])
                        continue;
