Span events not supported in Android

[generalpf]

Describe the bug

When you call OTelSpan.addEvent() (by way of Span.addEvent()) the event is silently dropped.

https://github.com/DataDog/dd-sdk-android/blob/develop/features/dd-sdk-android-trace-otel/src/main/java/com/datadog/opentelemetry/trace/OtelSpan.java#L83-L93

This is odd because the iOS SDK supports span events (which are just logs, correlated to the span).

I considered making this a feature request but given the fact that it fails silently without throwing an exception, and iOS has this functionality, it feels like a bug.

Reproduction steps

Create a span, then call addEvent() on it. The event (log) does not get sent to Datadog.

Logcat logs

No response

Expected behavior

The log should appear in Datadog, with a link back to the span. Looking at the span, you should be able to see the events that were sent while the span was in progress.
