Flush logs on crash

[stefanosiano]

📜 Description

When a crash occurs, logs are flushed

💡 Motivation and Context

We ensure to store logs to disk (or even send them) instead of losing them due to being only in memory when a crash occurs

💚 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.

🔮 Next steps

I'm not sure on this.
In theory we could wait for flushTimeoutMillis twice, once here and once to flush the crash.
In practice I expect this method to be instantaneous in Android, as it doesn't wait for them to be sent, and there shouldn't be many logs on Android anyway
