- Renamed option to `builtin_vulkan`, since that's the name of the library and if we were to add new components, we'd likely use that same option. - Merge `vulkan_loader/SCsub` in `vulkan/SCsub`. - Accordingly, don't use built-in Vulkan headers when not building against the built-in loader library. - Drop Vulkan registry which we don't appear to need currently. - Style and permission fixes.
