Fix T75908: Sculpt GPU Batches + Render Artifacts

When sculpting the GPU batches are constructed with only the required data
for a single viewport. When that viewport changes shading or coloring mode (object
to vertex) batches might not hold all the needed information.

There is also a case when you have two 3d viewport one in object color
mode and the other in vertex color mode that the GPU batches were
updated without any vertex colors.

In order to fix these category of issues this patch would always
construct the full GPU batches for sculpting.
