[TASK] Merge QueryView with QueryGenerator and move to lowlevel

The classes QueryView and QueryGenerator in the core extension
are detail implementations of the databases search functionality
of the lowlevel extension.
The patch merges both classes into one, moves it to the lowlevel
extension and deprecates the old classes. Minor refactorings like
protecting properties and methods is applied to the new class to
enable further refactoring if desired.
