CpsPath Query Optimization

- Optimized CpsPathqueries with descendants that only care about the xpath (no attribuets checks)
- Use native query with regular expression for target xpath and descendants
- Refactored so existing sql-geneartion code can be re-used in different repository implementations
- Adjusted related performance test expectations
