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.

Need to keep VkIcdSurface private to the loader.
The definition may conflict with some redefinitions of
VK_DEFINE_NON_DISPATCHABLE_HANDLE and it's not necessary to make public
anyway.

Use the ICD to create and destroy VkSurfaceKHR objects instead
of just performing the work in the ICD. This only occurs if the ICD
exports the appropriate entry-points, and exposes version 3 of the
loader/icd interface.

Per Khronos Bugzilla Bug 15077, on Windows and Linux, VkSurfaceKHR is treated
as a pointer to platform-specific structs that contain the platform-specific
connection and surface/window info. The Vulkan loader vkCreate*SurfaceKHR()
functions will fill in the struct. ICDs and layers will cast VkSurfaceKHR to a
pointer to the appropriate VkIcdSurface* struct.
