  Reland "Add support for Linux vulkan backend with VK_KHR_display"
  
  This is a reland of a7bb6a9b15ddeb8497523f8871deb25de2676d9f
  
  Original change's description:
  > Add support for Linux vulkan backend with VK_KHR_display
  >
  > Implement Linux simple display mode with vulkan backend
  > through VK_KHR_display.
  >
  > Added value 'EGL_PLATFORM_VULKAN_DISPLAY_MODE_SIMPLE_ANGLE' for
  > attribute EGL_PLATFORM_ANGLE_NATIVE_PLATFORM_TYPE_ANGLE to identify
  > the new simple display mode. Also reserved
  > EGL_PLATFORM_VULKAN_DISPLAY_MODE_HEADLESS_ANGLE for headless mode.
  >
  > How to enable:
  > Add
  >
  > ```
  > use_x11=false
  > angle_vulkan_display_mode="simple" # default value
  > ```
  >
  > into args.gn, then compile with linux vulkan args.
