Check in vulkan.h for generating framework code

Having copy of vulkan.h checked in makes it easier to re-generate
framework when needed.

vulkan.h is checked in as vulkan.h.in to discourage anyone from ever
attempting to include it directly in test code.

As part of this framework is updated to vulkan.h version 1.0.35.
