insert on duplicate语句不带列字段时出现空指针问题

[renliangyu857]

• I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

不带列字段时出现空指针，如insert into t values(1,1,1) on duplicate key update a = 2;

Ⅱ. Describe what happened

If there is an exception, please attach the exception trace:
定位到时在通过插入的数据构造前置镜像时，recognizer.getInsertColumns返回了null，在遍历时出现空指针问题；此时应该根据values构造主键查询列，参考BaseInsertExecutor#parsePKValuesFromStatement

Ⅲ. Describe what you expected to happen

Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. xxx
2. xxx
3. xxx

Ⅴ. Anything else we need to know?

Ⅵ. Environment:

• JDK version :
• Seata version:
• OS :
• Others:

insert into t_nounique values(3,3) on duplicate key update b = 5
这种sql需要根据matedata信息读到列的顺序去找到主键
