Use all_project_ids scope in VSA aggregation
What does this MR do and why?
This MR changes the VSA background aggregation scope to all_project_ids
so we can leverage the group hierarchy optimization:
- Before: https://console.postgres.ai/gitlab/gitlab-production-tunnel-pg12/sessions/25811/commands/81364
- After: https://console.postgres.ai/gitlab/gitlab-production-tunnel-pg12/sessions/25811/commands/81360
It shaves off about 120mb of buffers and improves the timings a bit.
