fix(android): Backfill exit options when app is unchanged

[romtsn]

📜 Description

Backfill release, environment, distribution, and app version data from the current options when persisted values are unavailable and the app has not been updated since an ANR or native crash.

Treat a missing or invalid package update timestamp conservatively so historical crashes are not attributed to the current app version.

💡 Motivation and Context

Exit events can be missing persisted option values. Current options are safe fallback values only when the installed app version has not changed since the exit; otherwise they can attach metadata from a newer release to an older crash.

💚 How did you test it?

• ./gradlew ':sentry-android-core:testDebugUnitTest' --tests='*ApplicationExitInfoEventProcessorTest*' --info (42 tests passed)
• ./gradlew spotlessApply apiDump

📝 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.
• Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.
