Unify cmake configuration generation experience

Currently Design Studio generates simple CMakeLists for Qt for MCUs project during project creation phase. 
Design Studio now also supports CMakeLists configuration generation for regular Qml/QtQuick projects for further transition into QtCreator.

Running Config Generation on MCUs project generates invalid configuration that doesn't align with the way Qt for MCUs application should be configured and build.

It can create confusion and should be improved on by unifying user experience with generating project configuration via following the same path.
