Fix Backward Incompatibility in schema_inference_make_columns_nullable Setting for Parquet/Arrow Formats

After https://github.com/ClickHouse/ClickHouse/pull/61984 schema_inference_make_columns_nullable=0 still can make columns Nullable in Parquet/Arrow formats. The change was backward incompatible and users noticed the changes in the behaviour. This PR makes schema_inference_make_columns_nullable=0 to work as before (no Nullable columns will be inferred) and introduces new value auto for this setting that will make columns Nullable only if data has information about nullability. #68298 (Kruglov Pavel).
