  EGL: Implement eglCopyMetalSharedEventANGLE
  
  Add eglCopyMetalSharedEventANGLE function to the
  ANGLE_metal_shared_event_sync extension. This brings the extension on
  par with the EGL_ANDROID_native_fence_sync extension.
  
  eglCopyMetalSharedEventANGLE allows for copying the Metal event object
  from EGLSync objects implemented by the ANGLE Metal renderer. This
  function follows Objective-C convention for "copy" methods and increases
  the retain count of the Metal event object. The EGL API user is thus
  responsible for ensuring to release the returned object to avoid memory
  leaks.
  
  Test: angle_end2end_tests --gtest_filter=EGLSyncTestMetalSharedEvent.*
