Removes use of iceberg.mr.schema.auto.conversion from documentation due to HIVE-26507

[linghengqian]

For #29052.

Changes proposed in this pull request:

• Removes use of iceberg.mr.schema.auto.conversion from documentation due to HIVE-26507 . See HIVE-26507: Do not allow hive to iceberg migration if source table contains CHAR or VARCHAR columns hive#3570 and HIVE-26507 (addendum): Do not allow hive to iceberg migration if source table contains CHAR or VARCHAR columns hive#3593 .
• Add nativeTest for connecting to HiveServer2 using ACID tables under GraalVM Native Image.
• Update the unreasonable Seata AT documentation. According to further investigation of third-party documents like https://www.yuque.com/linghengqian/meve2v/es8d3a8a18odao7x , it is not necessary to set global interceptors for all microservices.
• Introduces additions to initFile in HiveServer2 documentation to partially support the use of set statements.
• I personally don't understand why the unit test of HiveServer2 is so slow. Can't believe how slow HiveServer2 is without iceberg. I'm still investigating Hive's outdated LLAP and CBO documentation. The total number of SQLs executed by all databases is similar. There is nothing wrong with ZookeeperServiceDiscoveryTest. ZookeeperServiceDiscoveryTest is basically IcebergTest executed twice, and Zookeeper Server is started.
