[LFC][IFC] Paint partial trailing run with hyphen when needed
https://bugs.webkit.org/show_bug.cgi?id=204953
<rdar://problem/57705169>

Reviewed by Antti Koivisto.

When LineBreaker comes back with a partial content that needs hyphen, we need to make sure this information
ends up in the final Display::Run so that the rendered content includes the hyphen string. Note that this only needs to
be done when the content does _not_ have the hyphen already (opportunity vs. oppor-tunity).
(This patch also renames trailingPartial to partialTrailing because the fact that it is partial run is more important than that it is trailing run.)
