  Upstream WebKit's iOS port of ANGLE.
  
  Added the EAGL backend authored by Dean Jackson from Apple, and the
  refactoring changes needed to support it side-by-side with the macOS
  backend. Ran "git cl format" against these diffs.
  
  Defined the EGL_ANGLE_device_eagl extension and allocated an enum out
  of ANGLE's reserved range.
  
  The iOS backend is not yet included in any of the GN files.
  
  Bug: angleproject:4263
