  Reland "Vulkan: Implement EGL_EXT_device_drm[_render_node]"
  
  This is a reland of commit 8900cbf96a3127880b1667d2242dc13a98cfe029
  
  Original change's description:
  > Vulkan: Implement EGL_EXT_device_drm[_render_node]
  >
  > These extensions are needed by Exo for zwp_linux_dmabuf v4 support.
  >
  > Unfortunately `VkPhysicalDeviceDrmPropertiesEXT` doesn't give us the
  > information about the filesystem layout, needed by the EGL version.
  > As ChromeOS is currently the only user, implement the extension only for
  > Linux where we can reasonably assume `/dev/dri/...` file paths.
  >
  > We do not, however, limit us to the GBM backend - having the extension
  > working in e.g. a nested X11 or Wayland environment is quite helpful.
  >
