  Metal: Re-add end2end test configs (running test is still disabled)
  
  angle_test_instantiate.cpp & angle_test_instantiate_apple.mm:
  - Disabled metal platform selection on pre-10.13 mac devices for
  Bug: angleproject:4153
  
  Explicitly disabled tests on metal:
  - DifferentStencilMasksTest.DrawWithDifferentMask
  - PointSpritesTest.PointSizeAboveMaxIsClamped
  - WebGL2ReadOutsideFramebufferTest.CopyTexSubImage3D
  
  This requires the crash fix in http://crrev.com/c/1924101
