**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.
```

        return false;
    if (!right_storage_dictionary)

    auto dict_name = right_storage_dictionary->getDictionaryName();
    auto dict_key = getDictKeyName(dict_name, context);
    if (!dict_key.has_value() || *dict_key != it_key->second)
        return false; 
    Names src_names;
    NamesAndTypesList dst_columns;
    for (const auto & col : sample_block)
    {
        if (col.name == right_key)
            continue; 
        auto it = original_names.find(col.name);
        if (it != original_names.end())
        {
            String original = it->second;
            src_names.push_back(original);

        }
    }
