feat(core): Add gen_ai.conversation.id attribute to OpenAI and LangGr…

[RulaKhaled]

This PR adds support for capturing conversation/session identifiers in AI integrations to enable linking messages across API calls.

Changes

OpenAI

• Added instrumentation for the Conversations API (conversations.create)
• Captures gen_ai.conversation.id from:
  • conversation parameter in responses.create
  • previous_response_id parameter for response chaining
  • Response object from conversations.create

LangGraph

• Captures gen_ai.conversation.id from config.configurable.thread_id when invoking agents

Closes #18702

[linear]

JS-1409 Add `gen_ai.conversation.id` to supported AI integrations
