If a DrawGroup contained both inverted and non-inverted scale
the command generate shader would output the resource_id
content at conflicting indices. This is because the number of
instances stored inside the DrawGroup are the original
count before multiview. Actually, only start was taking the
multi-view count into account.

We cannot modify the value on CPU otherwise it would increase
the instance count for each submission. So the fix is to
pass the view count to the command generate shader and
multiply the instance count where needed.
