Add CMake Presets for Qt build and add auto-detection for Qt in Windows (#3141)

* add CMakePresets.json

* Update REUSE.toml

* fix vs

* impl

* adjust CMakeSettings.json

* add FindQt.cmake to reuse

* rename cmake file, add check before running cmake and add inheritation to presets

* add error check in cmake

* cleanup

* degrade not detected message and search only for x64 Qt
