In the 3.1 storage-computation separated version, using the INSERT INTO statement in Flink SQL will lose data with Delete semantics.
What type of PR is this：
Which issues of this PR fixes ：
Fixes #364
Problem Summary(Required) ：
In the storage-computation separated version, the primary key information is not stored in the information_schema.COLUMNS table, causing the Flink connector to fail to detect the primary key and assume that the StarRocks table does not support writing Flink delete rowkind data.
Solution: Determine whether to support delete semantics based on the primary key declaration in the Flink table.
