Ian Elliott 56f54c8a6b WSI-ICD: Created per-platform structs for platform-specific info.
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.
