  Vulkan: Output SPIR-V ids from compiler
  
  In this change, the shader interface variables are given SPIR-V ids by
  the compiler before SPIR-V generation.  Those ids are made available
  through the ShaderVariable interface.
  
  The transformer does not yet rely on this information.  A follow up
  change will rework the backend's name->info map and the transformer to
  directly use ids instead of names.
