Daemon Daemon-vulkan infrastructure 2

Adds some more cmake changes required for daemon-vulkan, slightly modified version of the Khronos Vulkan header generator, as well as a shader generator with support for #insert/#include and SPIR-V generation. Also added some of the embed stuff from #1842 with more functionality.

Most of the changes are just the XML spec and existing generator code.

VulkanHeaders seems to be a third-party library, so it should go in libs. Is there some good reason to check in the files directly instead of using a submodule?

Most of it is not used by daemon-vulkan.

So what is the future maintenance plan for VulkanHeaders: do we expect to maintain it ourselves or periodically sync updates from upstream?

Periodic sync. Header generator rarely ever gets updates and likely would continue working as is without issue.

OK cool. In any case it should go in libs/

Moved it.

slightly modified version of the Khronos Vulkan header generator,

If there are modifications of the files in libs/ relative to upstream, would you mind checking in the original upstream version as the first commit, and then the local changes as a second commit? That way we can see what was changed in the history.

Also I request that the commit hash of the Vulkan Headers repo be recorded in the commit message.

Sure, done.
