[FLINK-7552] [FLINK-7553] Enhance SinkInterface / Use in FlinkKafkaProducer
## What is the purpose of the change
Enhance `SinkFunction` with a way of retrieving the element timestamp. This
allows us to get rid of the hybrid nature of `FlinkKafkaProducer010`.
This is keeping the legacy static "convenience" methods à la
`FlinkKafkaProducer010.writeToKafkaWithTimestamps` for backwards compatibility.
