**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.

for (const auto & name : required_columns)
                prewhere_info->prewhere_actions->tryRestoreColumn(name);
            auto analyzed_result
                = TreeRewriter(context).analyze(required_columns_from_prewhere_expr, metadata_snapshot->getColumns().getAllPhysical());
            prewhere_info->alias_actions
                = ExpressionAnalyzer(required_columns_from_prewhere_expr, analyzed_result, context).getActionsDAG(true, false);
            
            auto required_columns_from_alias = prewhere_info->alias_actions->getRequiredColumns();
            Block prewhere_actions_result = prewhere_info->prewhere_actions->getResultColumns();
            for (auto & column : required_columns_from_alias)
                if (!prewhere_actions_result.has(column.name))
                    if (required_columns.end() == std::find(required_columns.begin(), required_columns.end(), column.name))
                        required_columns.push_back(column.name);
            
            for (const auto & column : required_columns_from_prewhere)
                if (required_aliases_from_prewhere.count(column) == 0)
                    if (required_columns.end() == std::find(required_columns.begin(), required_columns.end(), column))
                        required_columns.push_back(column);
        }
    }
