Below test case worked before 21.4. It seems there's parsing issue with all Map columns using Integer as key.
```sql
set allow_experimental_map_type = 1;
CREATE TABLE IF NOT EXISTS test_maps(ma Map(Integer, Array(String)), mi Map(Integer, Integer), ms Map(String, String)) ENGINE = Memory;
-- Exception on client:
-- Code: 62. DB::Exception: Cannot parse expression of type Map(Int32,Array(String)) here: {1:['11','12'],2:['22','23']},{1:11,2:22},{'k1':'v1','k2':'v2'}): data for INSERT was parsed from query
insert into test_maps values ({1:['11','12'],2:['22','23']},{1:11,2:22},{'k1':'v1','k2':'v2'});
```

Just tried 21.6 and it's still the same:
```sql
:) create table if not exists test_map_with_int_key(m Map(UInt32, UInt32)) engine = Memory;
...
:) SELECT CAST(([1, 2], [11, 22]), 'Map(UInt32, UInt32)') AS m;

SELECT CAST(([1, 2], [11, 22]), 'Map(UInt32, UInt32)') AS m

Ok.
:) insert into test_map_with_int_key values({1:11,2:22})

INSERT INTO test_map_with_in_key VALUES

```

P.S. I'll submit PRs for integration test this week so that we can spot this kind of issue early.
