  Add EGL GGP extensions.
  
  This CL adds two new extensions:
  
   * EGL_ANGLE_ggp_stream_descriptor:
      Introduces a new attribute to CreateWindowSurface. Allows the app
      to pass in a stream descriptor to VkCreateSurfaceKHR.
      Mirrors VK_GGP_stream_descriptor_surface.
  
   * EGL_ANGLE_swap_with_frame_token:
      Introduces a new function 'eglSwapBuffersWithFrameTokenANGLE'. This
      allows the app to pass a GGP frame token down to vkQueuePresentKHR.
      Mirrors VK_GGP_frame_token.

  Dependencies
  
      This extension is written against the wording of the EGL 1.5
      Specification.
  
  Overview
  
      This extension allows initializing an EGL Window surface backed by a
      VkSurfaceKHR with a Google Games Platform GgpStreamDescriptor.
  
      It is based on the Vulkan extension VK_GGP_stream_descriptor_surface.

  New Tokens
  
      Accepted as an attribute name in the <attrib_list> argument to
      eglCreateSurfaceKHR:
  
          EGL_GGP_STREAM_DESCRIPTOR_ANGLE  0x348B
  
  Additions to the EGL 1.5 Specification
  
      Add the following to section 3.5.1 "Creating On-Screen Rendering Surfaces":
  
      EGL_GGP_STREAM_DESCRIPTOR_ANGLE indicates a GgpStreamDescriptor referring
      to the GGP stream descriptor to associate with the surface. If
      EGL_GGP_STREAM_DESCRIPTOR_ANGLE is not specified a default stream
      descriptor will be used.
  
  Issues
  
      None yet.
