Discard envelopes on 4xx and 5xx response

[adinauer]

📜 Description

Envelopes are now discarded on a 4xx or 5xx response instead of retrying them.

• For 4xx it's most likely an SDK (e.g. incorrect serialization) or envelope problem (e.g. too large) where retry does not make sense.
• We decided to also not retry on a 5xx response in order not to take down Sentry by accumulating lots of envelopes in case of an outage where after restoring functionality Sentry is hit by too many requests.

💡 Motivation and Context

Fixes #4921
Fixes #4936

💚 How did you test it?

📝 Checklist

• I added GH Issue ID & Linear ID
• 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.
