GetInstancePorcAddr() is specified to return trampoline entrypoints for all
Vulkan core and extension entrypoints that are dispatched on an instance object
or a child of that instance object. However, typically, device extensions would
be unknown to the loader (don't want to rev the loader everytime an IHV creates
a new device extension).
This patch allows loader to dynamically discover device extension entrypoints
and configure generic trampoline code for these discovered device extensions.
Add a check to determine if the API version being requested can be
handled by the loader. If it can't, then we return incompatible driver.
If we can, we continue along our merry way.
An addendum is that we also bumped the Loader/ICD interface version.
This was requested by Nvidia so that the ICDs know that we pay attention
to the version in the loader. If they don't see the new Loader/ICD
interface version, they will handle the failing on all non-1.0 API
requests.

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.
