feat(otel): add opt-in options for supplemental AI SDK attributes on OpenTelemetry spans

[aayush-kapoor]

Background

we will most likely be deprecating the LegacyOpenTelemetry class. but for users that still need AI SDK specific attributes (not spans), we should consider adding an opt-in option that will allow users to log those attributes

this is for information that is not already conveyed through gen_ai spans/attributes

Summary

emit LegacyOpenTelemetry ai_* attributes in OpenTelemetry when users want to opt in

registerTelemetry(
  new OpenTelemetry({
    usage: true,
    providerMetadata: true,
    runtimeContext: true,
  }),
);

Manual Verification

verified by running the examples:

• examples/ai-functions/src/generate-text/anthropic/subagent-with-telemetry.ts
• examples/ai-functions/src/telemetry/otel/generate-text-tool-call.ts
