[vulkan] Create render passes for up to 32 views
Actually, only 29 are used because nvidia's drivers segfault when there are more than 29 views (regardless of the exact bit pattern in the view mask). This will allow rendering shadow maps in large batches, which should make for better GPU utilization.
