**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.

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.

query.setExpression(
                ASTSelectQuery::Expression::WHERE, makeASTFunction("and", query.prewhere()->clone(), query.where()->clone()));
        }
        query_analyzer = std::make_unique<SelectQueryExpressionAnalyzer>(
            query_ptr,
            syntax_analyzer_result,
            context,
            metadata_snapshot,
            NameSet(required_result_column_names.begin(), required_result_column_names.end()),
            !options.only_analyze,
            options,
            std::move(subquery_for_sets),
            std::move(prepared_sets));
        if (!options.only_analyze)
        {
            if (query.sampleSize() && (input_pipe || !storage || !storage->supportsSampling()))
                throw Exception("Illegal SAMPLE: table doesn't support sampling", ErrorCodes::SAMPLING_NOT_SUPPORTED);
            if (query.final() && (input_pipe || !storage || !storage->supportsFinal()))
                throw Exception(
                    (!input_pipe && storage) ? "Storage " + storage->getName() + " doesn't support FINAL" : "Illegal FINAL",
                    ErrorCodes::ILLEGAL_FINAL);
            if (query.prewhere() && (input_pipe || !storage || !storage->supportsPrewhere()))
                throw Exception(
                    (!input_pipe && storage) ? "Storage " + storage->getName() + " doesn't support PREWHERE" : "Illegal PREWHERE",
                    ErrorCodes::ILLEGAL_PREWHERE);
            
            for (const auto & it : query_analyzer->getExternalTables())
                if (!context->tryResolveStorageID({"", it.first}, Context::ResolveExternal))
                    context->addExternalTable(it.first, std::move(*it.second));
        }
