  Remove State::syncProgramTextures.
  
  Removes the concept of the program textures dirty object. Instead we
  use a set of dirty bits to represent dirty texture samples. We mark
  certain textures dirty and update state structures whenever there is
  a new Texture/Program/Sampler bound, or when Texture/Program/Sampler
  state changes.
  
  This is in preparation for making clearing the uncleared active
  textures into a dirty bit as well.
  
  Also includes new dirty bit handling for texture image units. These are
  a GLES 3.1 feature.
