EEVEE: Motion Blur: Fix shutter delta

EEVEE: Motion Blur: Make motion blur closer to cycles by evaluating 3 step

For now we always center the delta around the frame time. We store 2 motion
steps, one before and one after the current frame. However, this also means
storing 2 motion vectors for each pixels, doubling the vram usage of the
motion vector buffer.

This patch also cleanup some uneeded complexity. We use the motion vectors
as is and don't use a multiplier.

EEVEE: Motion Blur: Use orig_object->data instead of orig_data as key

This fix issue with some modifier setup

EEVEE: Implement deformation motion blur

This adds deformation motion blur by saving the vertex buffers of the
previous frame.

We modify the surface batch to pass the vert position as new attributes.

DRW: Batch Cache: Expose position vertex buffer to engine

This is in order to compute position deltas for motion blur. The engine
is responsible to handle the data. However it is not the owner of the data.
So a copy must be performed if the data needs to be kept accross frame.

GPUVertexFormat: Add Rename function

This is needed for motion blur.

GPUVertBuf: Add duplication function

EEVEE: Motion Blur: Rework object motion vector rendering

Object matrices are now stored in a GHash per object, similar to cycles.
The objects surfaces are not split per material anymore.

This approach is not supported for viewport.

This approach is much cleaner and will be able to easily support deforming
motion blur.

This approach also supports instances

EEVEE: Object Motion Blur: Initial Implementation

This adds object motion blur vectors for EEVEE as well as better noise reduction for it.

For TAA reprojection we just compute the motion vector on the fly based on camera motion and depth buffer.
This makes possible to store another motion vector only for the blurring which is not useful for TAA history
fetching.

The changes are quite simple. We just do an extra pass to write the motion vectors for opaque objects and
use the motion vector to do the motion blur sampling.

This does not improve the postprocess motion blur itself.

Viewport support is kind of a hack, relying on cached previously drawn objects states, and is to be enabled
through experimental support panel in userpref.
