  Refactor end2end test macros
  
  This is a foundational CL to enabling the end2end tests on swiftshader.
  
  Refactored infrastructure with new ANGLE_INSTANTIATE_TEST_ES*
  macros that will run tests over all various combinations of all
  platforms for different ES versions.
  
  Just skipping failing tests initially to get the refactor landed.
