Physics: debug renderer for AABB. Using common base for Box and AABB, as the primitives are the same, but only draw function differs.

Moved Profiler and debug draw from Physics to new DebugTools library. Also cleaned up the code and split renderer creation from resource manager.

DebugTools: render boxes with proper size. Cube and Square primitives have 2x2(x2) size, thus to render box with size 1x1(x1) we have to set scale to 0.5.

Physics: specify AABB by its minimal and maximal dimensions. Center + size was confusing for entering and also with bad performance for computing collisions.

DimensionTraits<dimensions>::MatrixType::scaling((axisAlignedBox.transformedMax()-axisAlignedBox.transformedMin())/2);
DebugTools: simplified and optimized internal shape rendering. All rendering code computed the transformation/projection matrix the same way, resulting in redundant calculations. Also the `transformationMatrix` parameter of internal draw() function was never used.

DebugTools: ShapeRenderer cleanup. * Added missing forward declarations. * Added getters and setters to ShapeRendererOptions class. * Cube primitive is indexed, modified the mesh creation accordingly. It now uses MeshTools, link the library to DebugTools. * Simplified resource handling so it's now handled in one place. It still needs to be thought out better.
