[ci] periodic "inclusive" releases w/ VulkanUtilityLibraries + VulkanHeaders

Something similar to this: https://git.crueter.xyz/scripts/VulkanUtilityHeaders

Where for each Vulkan version, this repository has a release that contains *both* the VulkanHeaders and VulkanUtilityLibraries sources and headers, combined as one. This would be useful alongside #315 for enforcing projects that vendor VUL/VH *have* to match the versions if they choose to use these releases.

I have an idea on how to do this in a manner that makes sense, but I'm not quite sure how the maintainers would want it done so I'm leaving my CI (that only grabs the string helper from here anyways) for reference.

Start with the linked VulkanUtilityHeaders example and the existing CI referenced in the issue. Review issue #315 for the related version-matching requirement, then determine how releases should combine VulkanHeaders with VulkanUtilityLibraries for each Vulkan version. Done means maintainers agree on the approach and periodic inclusive releases contain both source and header sets.
