  Adjust clip distance compiler state and validation
  
  The internal uniform, which is used for passing GL state on
  some platforms, could be removed by GL drivers when built-ins
  are not accessed; this may lead to failed frontend assertions.
  
  Refactored relevant compiler state and validation helpers to
  avoid ambiguous usage.
  
  Added ClipCullDistanceTest.Unused test.
