I only added bindings for VK_KHR_vulkan_enable2, I don't think there's much of a point in implementing the older VK_KHR_vulkan_enable extension nowadays, any up to date OpenXR runtime should provide the new one by now.
Since presumably this will be used with a wrapper library for Vulkan that includes its own code to deal with VkResult and e.g. signal a condition, I just return those as is and leave the Vulkan part of the bindings to the library user.
