KAFKA-4108: Improve DumpLogSegments offsets-decoder output format
This PR improves the output format of DumpLogSegments when the
`--offset-decoder` option is used for consuming `__consumer_offsets`,
especially when it comes to group metadata.
An example of the partial output with existing formatting:
```
key: metadata::console-consumer-40190 payload:
consumer:range:1:{consumer-1-20240b92-fbf4-44d5-bf8c-66b6d70c9948=[foo-0]}
```
An example of the same output with suggested formatting:
```
key: {"metadata":"console-consumer-40190"} payload:
{"protocolType":"consumer","groupMetadata.protocol":"range","groupMetadata.generationId":1,"assignment":"{consumer-1-20240b92-fbf4-44d5-bf8c-66b6d70c9948=[foo-0]}"}
```
