We can place them in bottom center of the toolbar buttons with
just CSS, no need to manually calculate the position (which
doesn't give the correct results if the toolbar is not visible).
Also add z-index for correct rendering inside TargetWidget,
not overlapped by the toolbar border (e.g. in the media dialog).

The popup gets hideously deformed in other cases. Getting it to work
would probably be difficult. Let's just not show it.

OOjs UI Popups position themselves automatically relative to their
$floatableContainer these days.
Also added explicit `$floatableContainer: this.$element` in the config
(although not strictly needed, since the parent node is used by
default, this makes the code more robust in case we move the popup
somewhere else in the DOM).

Tools only setup once now, and that is during the dummy surface
phase, so we have to setup the education popups then.

If a tool had an education popup bound to it, but it was
suppressed because the user has already seen it (according to
the cookie or localStorage), then clicking that tool would
cause a JS error.
Also remove a workaround for a ClippableElement problem
that appears to be unnecessary.
