[Logs 4] Send logs in batches

[adinauer]

#skip-changelog

📜 Description

Instead of sending each log event on its own immediately, we now batch them and send after 5s.

💡 Motivation and Context

💚 How did you test it?

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

I'll approve but I think someone else should double check the baggage logic.
