Add almost all examples to ExampleApp (#1511)

Browse Source 
* fix: delete generated designerExample_*.py files

designerExample.py loads designerExample.ui directly

* remove unused examples/utils.py

* add almost all examples in folder

* use mkQApp and don't set style nor palette

not needed for an example and also avoids a PyQt6 6.0 refcount bug in
app.setStyle()

* bold interesting examples

* test_examples.py needs to know about Namespace too

* Revert "remove unused examples/utils.py"

This reverts commit 2eddead459.

* categorize examples lists in utils.py
