URL: https://github.com/apache/flink/pull/16578
## What is the purpose of the change
This introduces the config option `execution.shuffle-mode` which is an enum

It replaces `table.exec.shuffle-mode` and allows to influence the
`GlobalStreamExchangeMode` for both DataStream API and Table API consistently.
## Brief change log
- Use `GlobalStreamExchangeMode.ALL_EDGES_BLOCKING` as new default for batch
mode

`table.exec.shuffle-mode`.
