feat(android): Add ApplicationStartInfo API support for Android 15+

[markushi]

📜 Description

Adds support for Android 15+ (API 35) ApplicationStartInfo API to collect detailed app startup timing data and create a custom transaction with enriched AppStartMetrics spans.

Key Features:

• Uses ActivityManager.addApplicationStartInfoCompletionListener() to capture startup data when current launch completes
• Creates transactions with op app.start.info and name app.start.{reason} (e.g., app.start.launcher)
• Includes detailed timing spans:
  • app.start.bind_application - Time from fork to bind application
  • app.start.application_oncreate - Time from fork to Application.onCreate
  • app.start.ttid - Time to initial display (first frame)
  • app.start.ttfd - Time to full display (fully drawn)
• Enriches with AppStartMetrics data:
  • Content provider onCreate spans with class names
  • Application.onCreate description with class name
• Tags include: start.reason, start.type (cold/warm/hot), start.launch_mode

Implementation Details:

• Opt-in feature via SentryAndroidOptions.setEnableApplicationStartInfo(boolean) (disabled by default)
• Uses completion listener approach (no historical data collection)
• All spans start from fork time showing cumulative timing

💡 Motivation and Context

Implements #6228

💚 How did you test it?

• Added comprehensive unit tests (11 tests in ApplicationStartInfoIntegrationTest)
• Added integration test in AndroidOptionsInitializerTest

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

• May add additional tags when more data becomes available in future Android API levels
