Rework setup, VS->FS structures, etc for Vulkan

- Remnants of old fixed function attributes all gone
- Initial support for some builtins to prove the model
- Setup now driven by correct shader state
- VS->FS intermediate structure matches SPIRV model -- builtins are not
in location space; location space itself is flat scalars rather than
vec4-oriented.

There are still some vertex pipe features which are not supported, as
ES3 didn't have them -- proper handling of noperspective, etc.
