CMakePM: Fix handling of qml debugging

Add a respective aspect to the build configuration
for handling qml debugging from the build side
similar to what we do with qmake and qbs.

Qml debugging needs to get enabled on the build side
before the settings on the run configuration page
has an effect.

Fixes: QTCREATORBUG-23541
