  Simplify formatutils.h by exposing the info structures.
  
  Removed all the separate query functions and simply expose the internal
  info structures.  This reduces the number of std::map/std::set operations
  that were hidden behind the API.
  
  Moved the validation tables for ES3 format combinations and effective
  internal formats into validationES3.cpp so that formatutils.h only has
  generic GL format queries.
