Graphical debug drawer

[Adnn]

A visual debug drawer is cool, but can quickly become noisy. Ideally, it would be controlled like logging:

• Channels.
• Severity.

It should provide:

• Line
• Plane
• 3D shapes (wireframe spheres, etc.)
  • Box
  • ~Sphere~
  • Arrow
  • Frame-of-reference
• Text
• ~Screen space / World space drawing~
• ~Depth test toggle~

Rework:

• [x] Renderer controls should be atomics (and reuse factorized funcs)
• [x] Handle the color of the annotation
• [x] Draw avocado bounding box
• [x] Separate between a DebugDrawer and a DebugRender(this one hosting the "shared" data)
• [x] remove DrawList::MakeEmpty()
• [x] Remove Renderer::mMeshInstance
• [x] Ability to disable debug drawing at compile time (or disable below a given level)
