  [IFC][Line clamp] Truncate non-overflowing content when line-clamp ellipsis does not fit the line
https://bugs.webkit.org/show_bug.cgi?id=248251

Reviewed by Antti Koivisto.

When line-clamp kicks in, the trailing ellipsis may produce content overflow.
handleLineEndingEllipsisPolicy checks if we need to truncate the initially non-overflowing content.

(WebCore::Layout::InlineFormattingContext::lineLayout): This is just moving lines around. No change in logic.
(WebCore::Layout::shouldTruncateOverflow): Deleted.
