Apparently apps like Google Play Services feel entitled to display notifications like "Update Phone Number!" that you can't dismiss and must act on to clear. I just discovered how to clear these:
Long press the notification and tap "(i)" to go into settings, turn on "Block all notifications from this app" and it will go away. Even if you turn that right back off again, as I did, that's enough to clear the pending notification without too much trouble.
