Add enableScopePersistence option

CHANGELOG.md

 ## Unreleased
 
+### Features
+
+- Add `enableScopePersistence` option to disable `PersistingScopeObserver` used for ANR reporting which may increase performance overhead. Defaults to `true` ([#3218](https://github.com/getsentry/sentry-java/pull/3218))
+  - When disabled, the SDK will not enrich ANRv2 events with scope data (e.g. breadcrumbs, user, tags, etc.)
+
 ### Fixes
 
 - Fix old profiles deletion on SDK init ([#3216](https://github.com/getsentry/sentry-java/pull/3216))
