  Add support for arrays of arrays in AST processing
  
  Data concerning arrays of arrays is added in TType.
  
  Parsing arrays of arrays and support for arrays of arrays in
  TPublicType are still left to be implemented later.
  
  ShaderVariable interface for arrays of arrays is also left to be
  implemented later.
  
  We rely on existing test coverage to make sure that arrays of arrays
  are not accidentally exposed.
  
  BUG=angleproject:2125
  TEST=angle_unittests, angle_end2end_tests, angle_deqp_gles31_tests
