The build is failing because the change to the spec that has been made is backwards incompatible; older headers don't define VK_BASE_* / etc. macros.
I will have to wait for Vulkan-Headers update to figure out how to best fix that; at the minimum generate.py will need to change to remove this nonsense, but I'm not sure if the macros will stay in the new header versions or would need to be redefined in a hacky way by volk itself.

Oh also they haven't bumped the spec version, yay. 1.4.329 is already a thing. I'll close this PR and disable the cron job for now.

Looks like removing VK_BASE_* fixes the diff for now, so maybe that will be enough as the XML still defines the old style version macros. Will push this to re-enable the updates.
