  Reland "GLES1: Entry points for lighting and materials"
  
  This is a reland of 4a09c1a245c406e402b3996b7ed33798b897e60f
  
  Entry points have been autogenerated again.
  
  Original change's description:
  > GLES1: Entry points for lighting and materials
  >
  > - glLight*/glMaterial and their queries
  > - Use new packed enums in these entry points, except for lightmodel
  > which stays GLenum to be consistent with other generic glGet's
  > - State.cpp: New glGet* queries related to light model and
  > light/normal rescale enablement
  > - GLES1State.cpp: Functions to get/set lighting/material state
  > - Validation for lighting/materials
  >
  > + Add a few convenience methods to random_utils for sampling
  > non-negative floats and a sampler for random booleans
  >
