[POC] FieldSerializer for Records

[theigl]

This is a POC for moving record serialization from RecordSerializer into FieldSerializer.

This approach has two main advantages:

1. Existing configuration options for the FieldSerializer can be used for records
2. Sub-classes of FieldSerializer (Compatible, Versioned, Tagged, ..) can be adjusted for records

JDK 17+ is required for this PR so it is a likely candidate for the next major version.

Sorry to jump on a PR - let me know if I should post somewhere else.

I'm currently looking at serializing records with Kryo with the requirement that I have forward/backward compatibility. I've tested using this branch and it does exactly what I need, so I'd like to know the best way to move forward:

• wait for the next major release which includes this change, but I haven't seen anything published as to when that might be
• fork the repo and build my own version separately but I'd rather avoid this if possible
• extract the record serialization and create a separate serializer I can use for records, with the intention to remove it when the next major version is released

I appreciate any advice on the best way forward
