ref(android): Remove the enablePerformanceV2 option

CHANGELOG.md

@@ -52,6 +52,9 @@
 - `SentryUserFeedbackForm` now extends `android.app.Dialog` instead of `android.app.AlertDialog` ([#6338](https://github.com/getsentry/sentry-java/pull/6338))
   - The form never used `AlertDialog` features. Code that calls `AlertDialog`-only methods on it, such as `setButton` or `setMessage`, no longer compiles.
 - `sentry-android` no longer includes `sentry-android-ndk` as a default dependency. Instead, tombstone reporting is enabled by default, which provides more detailed native crashes on Android 11+ (API 30). If you're using sentry-android-ndk APIs, or need native crashes on Android 10 and lower, manually add the `io.sentry:sentry-android-ndk` dependency to your app. ([#6436](https://github.com/getsentry/sentry-java/pull/6436))
+- Remove the Android `enablePerformanceV2` option and its `io.sentry.performance-v2.enable` manifest metadata. Performance V2 is always on ([#6458](https://github.com/getsentry/sentry-java/pull/6458))
+  - App starts are measured from process start on Android 7.0+ (API 24), and slow and frozen frames are measured per span
+  - `ActivityFramesTracker` is removed, and the `ActivityLifecycleIntegration` constructor no longer takes it
