  Vulkan: Create instance/device without access to Display
  
  The feature overrides are now encapsulated in a struct, a reference to
  which is passed around until features are initialized.  Additionally,
  some window system information needed to decide which extensions to use
  or workarounds to apply are passed around.
  
  This is a step towards decoupling RendererVk from egl::Display for
  direct use with OpenCL.
