This module allow tracking of object and geometry data accross time. This commit adds no user visible changes. It work in both viewport (*) and render mode, gives correct motion for any camera projection type and is compatible with displacement (**). It is a huge improvement upon the old EEVEE velocity which was only used for motion blur and only available in render. It is also an improvement for speed as the animated objects do not need to be rendered a 3rd time. The code is also much cleaner: no GPUVertBuf duplication, no GPUBatch amendment, no special cases for different geometry types, no DRWShadingGroup per object, no double buffering of velocity. The module is still work in progress as the final output may still be flawed. (*): Viewport support is already working but there might be some cases where mapping will fail. For instance if topology changes but not vertex count. (**): Displacement does not contribute to motion vectors. Surfaces using displacement will have the same motion vectors as if they were not displaced.
