  Vulkan: Implement shader compilation.
  
  This hooks up the Vulkan GLSL, decorated with locations, to glslang,
  and then pipes the SPIRV back to the Program implementation for later
  use when making pipelines to run draw calls.
  
  The program compilation tests work now, but don't really test
  anything other than not generating Vulkan validation layer errors
  during compilation and shader object generation.
