anv: Return trampoline entrypoints from GetInstanceProcAddr
Technically, the Vulkan spec requires that we return valid entrypoints
for all core functionality and any available device extensions. This
means that, for gen-specific functions, we need to return a trampoline
which looks at the device and calls the right device function. In 99%
of cases, the loader will do this for us but, aparently, we're supposed
to do it too. It's a tiny increase in binary size for us to carry this
around but really not bad.
