POTEL 62 - Build PropagationContext from sampling decision

[adinauer]

📜 Description

Build PropagationContext from SamplingDecision made by SentrySampler instead of parsing headers and potentially ignoring a sampling decision in case a sentry-trace header comes in with deferred sampling decision.

💡 Motivation and Context

Support deferred sampling decision

💚 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.
