  Remove Context::gatherParams.
  
  This won't be used in the future. It saves a few instructions on each
  entry point.
  
  Also refactors a bit of touched code. Also adds in a missed entry
  point: "glTexStorage2DMultisampleANGLE".
  
  Removes related code and moves remaining helper code in params.h into a
  new file entry_point_utils.h.
  
  In total this patch series reduces overhead by up to 5%.
  
  Bug: angleproject:2933
