URL: https://github.com/apache/flink/pull/17230
Cherry-pick #16239
## What is the purpose of the change
After FLINK-22901.
We can use upsert keys to fix upsert join, upsert rank, and upsert sink.
- For join and rank: if input has no upsert keys, do not use upsert
optimization.
- For upsert sink: if input has unique keys but no upsert keys, we need add
a materialize operator to produce upsert records.
## Brief change log
- Join should use upsert keys instead of unique keys to do upsert
- Rank should use upsert keys instead of unique keys to do upsert
- TemporalJoin should use upsert keys instead of unique keys to do upsert
- Introduce materialize operator to produce upsert records before sink.
