HappenLee 2cc670dba6 [fix](vectorized) Support outer join for vectorized exec engine (#10323 )

In a vectorized scenario, the query plan will generate a new tuple for the join node.
This tuple mainly describes the output schema of the join node.
Adding this tuple mainly solves the problem that the input schema of the join node is different from the output schema.
For example:
1. The case where the null side column caused by outer join is converted to nullable.
2. The projection of the outer tuple.

Apache Doris

Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. Its original name was Palo, developed in Baidu. After donated to Apache Software Foundation, it was renamed Doris.

Doris provides high concurrent low latency point query performance, as well as high throughput queries of ad-hoc analysis.
Doris provides batch data loading and real-time mini-batch data loading.
Doris provides high availability, reliability, fault tolerance, and scalability.

The main advantages of Doris are the simplicity (of developing, deploying and using) and meeting many data serving requirements in a single system. For details, refer to Overview.

Technology

Doris mainly integrates the technology of Google Mesa and Apache Impala, and it is based on a column-oriented storage engine and can communicate by MySQL client.
