Fix native-only thread dump parsing and tracingContext for ANRv2

[romtsn]

📜 Description

• Fixes thread dump parsing for native-only thread dumps
• Fixes TracingContext envelope header for ANRv2 events (we derive values from the backfillable event now instead of Scope)

💡 Motivation and Context

💚 How did you test it?

Manually and automated

📝 Checklist

• I reviewed the submitted code.
• 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.
• 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.
