  vkd3d: Mask colour writes on graphics pipelines without fragment shaders.
  
  Vulkan leaves the contents of colour attachments undefined in this case.

  vkd3d: Get rid of the default fragment shader from d3d12_pipeline_state_init_graphics().
  
  Vulkan does support rendering without a fragment shader, and this seems
  to work fine on current drivers. This commit gets rid of the last
  embedded shader binary in libvkd3d, and may have a slight performance
  advantage on hardware/drivers able to take advantage of the absence of a
  fragment shader.
