Mirror AttributeName enum changes to Broker repo (ad-accounts-for-android)

[Copilot]

The AttributeName enum in common4j requires all changes to be mirrored in the Broker repo's corresponding enum for cross-repo telemetry key consistency. PRs #3074 and this stacked PR introduced additions and a removal that were not reflected in AzureAD/ad-accounts-for-android.

Changes needed in Broker AttributeName.java

• Add elapsed_time_cache_delete_access_tokens_with_intersecting_scopes — new timing attribute from Optimize token cache remove path and add filter-first-clone flight for filtered retrieval, Fixes AB#3570409 #3074
• Remove elapsed_time_save_account_shared_preferences — deleted in Optimize token cache remove path and add filter-first-clone flight for filtered retrieval, Fixes AB#3570409 #3074 (unused after save-path optimization)
• Add is_filter_then_clone_enabled — boolean flag attribute indicating whether the filter-then-clone flight is active during getCredentials()/getAccounts()

Note: AzureAD/ad-accounts-for-android is private and not accessible from this environment. The exact code snippets have been posted on the triggering review comment for a developer with Broker repo access to apply.
