loader: Update the loader to 1.0.39

Add new extensions for 1.0.39.  Also, updated layers to include
minimal set of functionality for 1.0.39 extensions. Extensions include:
 - VK_KHR_get_physical_device_properties2
 - VK_KHR_shader_draw_parameters
 - VK_EXT_direct_mode_display
 - VK_EXT_display_surface_counter
 - VK_EXT_display_control

Also, redo the LoaderAndLayerIf document.
