(Sight): Qt3D SMaterial adaptor

Description

Implement qt3d material service:

• ::fwRenderQt3D::data::Material object handling a qt3d material
• ::fwRenderQt3D::techniques::Lighting object handling a qt3d technique with shader programs to compute lighting mode and rendering options such as point/line/surface rendering or normals visualization
• ::fwRenderQt3D::SMaterial adaptor used to create a qt3d material from sight data and attach it to the render service

Closes #495 (closed)

How to test it?

These features can be tested using one of these applications:

• TutoSceneQt3D
• TutoSceneQt3DCpp
• TutoSceneQt3DQml

These apps load a mesh (using Ctrl+O) and render it into a generic qt3d scene.
