[QA] Lazily load SentryOptions members

CHANGELOG.md

@@ -20,6 +20,7 @@
     - If you're using code obfuscation, adjust your proguard-rules accordingly, so your custom view class name is not minified
 - Fix ensure Application Context is used even when SDK is initialized via Activity Context ([#3669](https://github.com/getsentry/sentry-java/pull/3669))
 - Fix potential ANRs due to `Calendar.getInstance` usage in Breadcrumbs constructor ([#3736](https://github.com/getsentry/sentry-java/pull/3736))
+- Lazily initialize heavy `SentryOptions` members to avoid ANRs on app start ([#3749](https://github.com/getsentry/sentry-java/pull/3749))
