[Development] Moving math3d classes from GUI to CORE

Indeed, getting some of the SSE work from Qt 3D into Gui could be useful as well.

When it comes to 3rd party solutions, the graphics stack would most likely be fine and happy with using glm (and so math3d could just go away), but that would mean pulling in more 3rd party dependencies, which is not necessarily ideal either. (in any case, that's a topic to be discussed separately)

And yes, Eigen is probably a good example of something Qt should not be pretending to be competing with.

as does Qt3D
