Notes: * Code in rendering and in game engine will still convert tangents to a tessface representation. Added code that takes care of tangent layer only, might be removed when BGE and rendering goes full mlooptri mode. * Baking should work discovered some dead code while I was working on the patch, also tangents are broken when baking from multires (also in master), but those are separate issues that can be fixed later. This should fix T45491 as well
