perf(android): Replace RNSentryFrameDelayCollector with sentry-java getFramesDelay API

[antonis]

📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

Replaces the custom RNSentryFrameDelayCollector (listener-based frame delay collector) with a direct call to the new SentryFrameMetricsCollector.getFramesDelay() API added in sentry-java#5248 (commit 61659b6).

Changes:

• Delete RNSentryFrameDelayCollector.java (~130 lines) — no longer needed
• Simplify fetchNativeFramesDelay() to call collector.getFramesDelay(startNanos, endNanos) directly
• Replace custom listener with a no-op listener registration to ensure frame metrics collection stays active
• Add stopFrameMetricsCollection() helper for clean lifecycle management

💡 Motivation and Context

Closes #5908

The previous implementation in #5907 duplicated work already done internally by sentry-java:

• Double listener callbacks: Every frame triggered two listener callbacks on the UI thread
• Double storage: Two separate data structures holding the same per-frame delay records
• Redundant computation: Both collectors computed delay overlap independently

With sentry-java now exposing a queryable API (mirroring iOS's getFramesDelaySPI), we can eliminate all of this overhead.

⚠️ Blocked on sentry-android SDK bump

This PR requires sentry-android >= next release (> 8.40.0) which includes the getFramesDelay() API and SentryFramesDelayResult class. It will not compile against the current 8.40.0 dependency.

💚 How did you test it?

• All JS/TS tests pass (yarn test — 1187 tests)
• Code review of the API surface against sentry-java#5248
• Will require integration testing once sentry-android is bumped

📝 Checklist

• I added tests to verify 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.
• All tests passing
• No breaking changes

🔮 Next steps

• Bump sentry-android dependency to the release containing getFramesDelay() API
• Verify Android compilation and run integration tests
• Consider removing the no-op listener if sentry-java's auto-instrumentation keeps collection active by default
