  Make Display and X11 available in the same build
  
  Chromium can use the 'use_ozone' and 'use_x11' build flags
  simultaneously, so we need the Vulkan display to still be
  selectable, even when the 'use_x11' flag is used.
  
  This is required to make SwANGLE work with Ozone/Wayland, which
  is going to use EGL_PLATFORM_VULKAN_DISPLAY_MODE_HEADLESS_ANGLE
  when SwANGLE is requested.
