This CL ensures that when <vulkan/vulkan.h> is included, the
appropriate VK_USE_PLATFORM_XXX macro is defined to enable the
declaration of platform-specific types and extensions.
Note that for Linux, this requires an xlib_with_undefs.h header
to remove annoying macros that are defined by <X11/X.h> (i.e.
Success, Always, None) and which prevent compilation of other
Dawn sources that use the same symbols as enum value names.
