  Vulkan: Prefer the local vulkan loader over the system one.
  
  Load the Vulkan loader ourselves and give vkGetInstanceProcAddr to
  volk. This allows us to always prefer loading from the current module
  directory instead of using the platform-specific ordering.
  
  Refactor angle::Library loading to use ModuleDir instead of
  ApplicationDir.
