Move TreeGridFilteringStrategy from grids to core

- Moved tree-grid.filtering.strategy.ts to core/data-operations/tree-grid-filtering-strategy.ts
- Updated all imports in grids to use igniteui-angular/core
- TreeGridFilteringStrategy is a data operation utility, belongs in core
- This eliminates the last runtime circular dependency between core and grids

Core now has ZERO runtime imports from grids - only type-only imports!
