  video: Add Vulkan support for vivante fb
  Vivante drivers use the VK_KHR_display extension for rendering directly
  to the frame buffer. This patch adds support to the video driver for
  Vulkan rendering using that method.
  
  - Add an utility function SDL_Vulkan_Display_CreateSurface that creates
  a surface using this extension. The display to use (if there are
  multiple) can be overridden using the environment variable
  "SDL_VULKAN_DISPLAY".
  
  - Use this function in a new compilation unit SDL_vivantevideo.c,
  which implements the SDL_VIDEO_VULKAN methods of the driver structure.
