Report active Spring profiles in envelope item context

[lcian]

📜 Description

Adds an EventProcessor that attaches the list of active Spring profiles (empty list if only the default profile is active) to all sent envelope items.
This information is set as data on a new dedicated Spring Context.

💡 Motivation and Context

Part of #4041

💚 How did you test it?

Unit tests to check that the EventProcessor is registered and that it behaves correctly, tested context application and serialization as well.

📝 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.
