**Describe what's wrong**

If you have more than 2 row policies with the same column used in conditions, ClickHouse tries to rewrite them in IN clause, but it doesn't work.

**Does it reproduce on recent release?**

Yes. 
ClickHouse 21.11, 21.8

**How to reproduce**

```
CREATE TABLE test_row
(
    `key` UInt32,
    `value` UInt32
)
ENGINE = MergeTree
ORDER BY key;

INSERT INTO test_row SELECT
    number,
    number
FROM numbers(10);

CREATE ROW POLICY IF NOT EXISTS key_1 ON test_row FOR SELECT USING key =1 TO default;
CREATE ROW POLICY IF NOT EXISTS key_2 ON test_row FOR SELECT USING key =2 TO default;

 SELECT * FROM test_row;

SELECT *
FROM test_row

Query id: c282f548-cf06-45b6-a187-b0ee37062514

┌─key─┬─value─┐
│   1 │     1 │
│   2 │     2 │
└─────┴───────┘

2 rows in set. Elapsed: 0.005 sec.

CREATE ROW POLICY IF NOT EXISTS key_3 ON test_row FOR SELECT USING key =3 TO default;

SELECT *
FROM test_row


0 rows in set. Elapsed: 0.017 sec.

SET optimize_min_equality_disjunction_chain_length = 10;

SELECT *
FROM test_row
WHERE 1

```

**Expected behavior**

Query works.


**Additional context**

Looks like that or chain rewrite doesn't work correctly for row policies.

const Settings & settings = context->getSettingsRef();
    for (size_t i = 0; i < windows_sorted.size(); ++i)
    {
        const auto & w = *windows_sorted[i];
        
        
        
        
        if (!w.full_sort_description.empty() && (i == 0 || !sortIsPrefix(w, *windows_sorted[i - 1])))
        {
            auto sorting_step = std::make_unique<SortingStep>(
                query_plan.getCurrentDataStream(),
                w.full_sort_description,
                settings.max_block_size,
                0 ,
                SizeLimits(settings.max_rows_to_sort, settings.max_bytes_to_sort, settings.sort_overflow_mode),
                settings.max_bytes_before_remerge_sort,
                settings.remerge_sort_lowered_memory_bytes_ratio,
                settings.max_bytes_before_external_sort,
                context->getTemporaryVolume(),
                settings.min_free_disk_space_for_temporary_data);
            sorting_step->setStepDescription("Sorting for window '" + w.window_name + "'");
            query_plan.addStep(std::move(sorting_step));
        }
        auto window_step = std::make_unique<WindowStep>(query_plan.getCurrentDataStream(), w, w.window_functions);
        window_step->setStepDescription("Window step for window '" + w.window_name + "'");
        query_plan.addStep(std::move(window_step));
    }
}
