📜 Description

Apply the resolved user information policy when generating Android's default installation-backed distinctId.

Move default distinctId generation out of AndroidOptionsInitializer and run it after the programmatic SentryAndroid.init callback. Generate the installation ID only when no distinct ID is configured and dataCollection.userInfo allows automatic identity collection.

Existing runtime gates in Android event, exit-info, device-context, and hybrid scope enrichment remain unchanged.

💡 Motivation and Context

Android logs and metrics use distinctId as an automatic user.id fallback when no scope user exists. The previous unconditional default generation left that SDK-generated identity available even when applications explicitly configured dataCollection.userInfo=false.

Evaluating the policy after the programmatic callback prevents automatic distinctId generation for opted-out applications while preserving custom IDs and the legacy absent-Data-Collection behavior.
