text: Title: [Usage collection] Remove deprecated rollups

  In 8.0.0, we should have safely deleted the following rollup logic in the `kibana_usage_collection`:
  
  - [ ] Application Usage's transactional to daily rollups: https://github.com/elastic/kibana/blob/4681a80317176543535bfdb2188d94aa40d741fc/src/plugins/kibana_usage_collection/server/collectors/application_usage/rollups/daily.ts
  - [ ] UI Metrics to UI Counters rollup: https://github.com/elastic/kibana/blob/577ccfb6f8fbb56e9c2d8de4daccc0698773fa6f/src/plugins/kibana_usage_collection/server/collectors/ui_counters/rollups/rollups.ts#L40-L90
