feat(android): Add log flushing on app backgrounding

[markushi]

📜 Description

Adds log flushing functionality that triggers when the Android app transitions to the background.

In favor of the more complicated old PR #4873

💡 Motivation and Context

Reduced data loss

💚 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.
