  Vulkan: Isolate DisplayVk.h from Display.cpp.
  
  With this change we no longer can access Vulkan (or Volk) headers
  in the ANGLE front-end. The only header that needs to be visible is
  the new "DisplayVk_api.h".
  
  This will simplify a bit of Volk integration.
  
  Also reworks how the entry points and headers are exposed to the tests.
