  Reland "EGL: Implement EGL_KHR_no_config_context"
  
  Add extension string and flag to all renderers that pass
  Modify eglCreateContext to accept EGL_NO_CONFIG
  Modify eglQueryContext per specification
  Modify eglMakeCurrent to bypass surface-context config compatibility checks
  Add check for client API
  Create new end2end test EGLNoConfigContextTest
  Disable on most renderers to prevent possible fail with future configs
  
  Bug: angleproject:3635
  Test: dEQP-EGL.functional.create_context.no_config*
        angle_end2end_tests --gtest_filter=EGLNoConfigContextTest*
