**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 (const auto & onexpr : table_join->getClauses())
    {
        JoinCommon::checkTypesOfKeys(block, onexpr.key_names_left, right_table_keys, onexpr.key_names_right);
    }
}
void HashJoin::joinBlock(Block & block, ExtraBlockPtr & not_processed)
{
    for (const auto & onexpr : table_join->getClauses())
    {
        auto cond_column_name = onexpr.condColumnNames();
        JoinCommon::checkTypesOfKeys(
            block, onexpr.key_names_left, cond_column_name.first,
            right_sample_block, onexpr.key_names_right, cond_column_name.second);
    }
    if (kind == ASTTableJoin::Kind::Cross)
    {
        joinBlockImplCross(block, not_processed);
