Support the GenAI semantics

[patwlan]

Is your feature request related to a problem? Please describe.
Hi,
we would like to support the Generative AI spans and event in our java/kotlin application.
For the most part this seems straight forward, but i believe there are certain parts that cannot be implemented with the current sdk.
For examplel the events require a body
https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-events/, that does not seem available.
(Correct me if i am wrong).

Describe the solution you'd like
Extend the java sdk to enable the implementation of the Generative AI spec.
https://opentelemetry.io/docs/specs/semconv/gen-ai/

Describe alternatives you've considered

I think what you're asking here is to have a stable Events API. We'll make that happen when the specification stabilizes and we have clear direction on how to implement Events. At the moment, it's not stable. We're actively involved in the stabilization process, including providing prototypes of various options. Thanks for your patience!

The events api was deprecated, and will only exist in the java core repo as an addition to the existing logging apis. That is, there will be the ability to set the event name on the log record, and there will be the ability to set "complex attributes" (nested structures within log attributes) once #7123 lands.

Please keep in mind that the docs that discuss "body fields" are outdated. The content of events has been decided to be placed into attributes. I'll raise this with the logging sig.
