Fixing performance issue with Proximity Detector (#23557)

* fixing access levels and removed strings from data defs

* Fixing proximity detector performance

- Re-added component filtering for the close entity search.
- Changed criteria functionality to only allow for searching for entities with all specified comps (matching any would be too unperformant)
