[vulkan] Recreate lighting pvs sets when loading lights 

Sets never shrink, so assigning a dynamically created set to a
statically created set after the working size has reduced (going from
demo2 to demo3) causes the set code to attempt to resize the statically
created set, which leads to libc having a bad time.
