Allow the Android Gradle plugin to provide authoritative manifest metadata so SDK initialization can skip PackageManager and Bundle unparceling. Read the injected map directly to avoid conversion overhead. Refs JAVA-531 Co-Authored-By: Codex <noreply@openai.com>

LGTM from the sentry-java side. i just had one thought but not sure how feasible it is.

📜 Description
Use manifest metadata injected by the Sentry Android Gradle plugin when available. The existing PackageManager Bundle remains the fallback, and all existing runtime option precedence remains unchanged.
💡 Motivation and Context
Reading ApplicationInfo metadata and converting every manifest option during startup showed up prominently in customer traces. The paired plugin change in getsentry/sentry-android-gradle-plugin#1405 resolves typed metadata from the final merged manifest and avoids that runtime work, reducing median SDK initialization time by 6.5% in the all-options benchmark.
💚 How did you test it?
Ran the ManifestMetadataReader release unit tests, including typed generated values, absent keys, auto-init, PackageManager fallback, and no Context access on the generated path. Also ran spotlessApply and apiDump.
📝 Checklist
🔮 Next steps
Release with getsentry/sentry-android-gradle-plugin#1405 to enable the generated path.
