Revert "[LayoutNG] Fix hyphens when rewinding occurs"

This reverts commit 957329b6eeba01be943a4991c8bd082a87ac1417.

Reason for revert: r708894 fixed the case where hyphens are
not rendered under certain conditions, but caused the
infinite rewind loop in |NGLineBreaker| when there are
negative margins on inline boxes.

This patch reverts the fix. I will work on the new fix for
the issue 1015297 after this revert.

Original change's description:
> [LayoutNG] Fix hyphens when rewinding occurs
>
> This patch removes |NGLineInfo::LineEndFragment|, which was
> introduced to support hyphens and ellipsis with the single
> code. However, ellipsis was changed to use different code,
> and |LineEndFragment| ended up with non-optimal way to handle
> hyphens.
>
> Although hyphens appear at most once in a line, storing this
> to |NGLineInfo| makes harder to keep it in sync with the
> hyphenated item. This patch changes it to a field in
> |NGInlineItemResult|.
