Extract useClickOutsideCallback hook from 2U

Is your feature request related to a problem? Please describe.

UIs that present 'modal' or 'popover' behavior often overlook an important UX element—dismissing the overlay UI when the user tries to access the UI behind it.

2U has a hook that takes an element ref, and a callback, and then calls that callback whenever a click is detected outside of the element. This could be a building block for modal behaviors—a simple solution for an important detail that is easy to overlook.
