✅ This PR depends on #17625 and it should be reviewed only after that one is merged.

This PR adds:

  1. Streaming support for Google GenAI sdk instrumenting the following methods:

    1. Models API Streaming

      • models.generateContentStream() - Stream content generation with real-time chunks
    2. Chat API Streaming (chats.create)

      • chat.sendMessageStream() - Stream chat responses with conversation context
  2. New tool calls attributes

    • GEN_AI_REQUEST_AVAILABLE_TOOLS_ATTRIBUTE - Captures available tools from requests
    • GEN_AI_RESPONSE_TOOL_CALLS_ATTRIBUTE - Captures function calls from responses
