Function loader.

Vulkan function from scratch loading happens in 3 stages - the first one is before any initialization has happened, and you have neither an instance structure nor a device structure. At this stage, you can only get the bare minimals to initialize an instance. The second stage is when you have an instance. At this stage, you can initialize a VkDevice, and have an idea of what extensions each device supports. Finally, in the third stage, you can proceed and load all core functions, plus you can be sure that any extensions you've enabled during device initialization will be available.
