Introduce Studio3DEngine and Layer3D

...and the ImGui integration for Qt Quick since in the new world Qt 3D is
not used to create the final, composited image and therefore the profile
ui must be moved over to be rendered by Qt Quick.

Each Layer3D has hard-coded content for now (a camera, a light, and a
sphere model).

The new types are marked as internal for the time being.
