Makefile to import generated scripts and headers when doing a spec update

Motivated by recent problems building the SC 1.0.15 spec update - will
import to VulkanSC-Headers and tweak once it's proven out for
Vulkan-Headers.

The Makefile may need to be modified when directory structure is changed
or new files are added.
