  Vulkan: Fix handling of inactive fragment outputs
  
  These were never assigned a location.  They are now removed by the
  translator similar to other inactive variables.

  // RemoveInactiveInterfaceVariables.h:
  //  Drop shader interface variable declarations for those that are inactive.  This step needs to be
  //  done after CollectVariables.  This avoids having to emulate them (e.g. atomic counters for
  //  Vulkan) or remove them in glslang wrapper (again, for Vulkan).
  //
  //  Shouldn't be run for the GL backend, as it queries shader interface variables from GL itself,
  //  instead of relying on what was gathered during CollectVariables.
