  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.
