  Metal: Use MTLEvent instead of MTLSharedEvent when possible
  
  Refactor mtl::Sync to be abstract and have multiple implementations
  using either MTLEvent or MTLSharedEvent. Use MTLEvent in all cases
  except for EGL Syncs when the user sets the sync type to
  EGL_SYNC_METAL_SHARED_EVENT_ANGLE.
  
  Determine completion of the sync object by watching for completion of
  the command buffer where the event's signaling was enqueued. Avoid any
  sleep loops by waiting on a condition_variable which is notified
  when the completed queue serial is updated.
  
  Forked from CLs by sky@ and kbr@
