Remove the dead `links` field from TextLayout (#686)

cc for awareness @mwcampbell.

That field was dead code left behind when we removed previous links
support. On that struct is probably not the right field for links to
live, since `Label` also uses `TextLayout`, but can't meaningfully
support links as part of a different interactive widget.
