[text-wrap-style:pretty] improve orphan avoidance heuristic.
https://bugs.webkit.org/show_bug.cgi?id=288236
<rdar://145318314>
Reviewed by Alan Baradlay.
This PR improves the orphan avoidance heuristic for text-wrap-style:pretty by
targeting a minimum of 2 inline items for the last line. This is done by
updating
computeCostPretty to automatically accept breaking points that would create an
acceptable last line without causing excessive line shrinkage. In addition,
this PR
also updates layoutSingleLineForPretty() support orphan avoidance by shortening
the
layout range by lastLinePreferredInlineItemCount to prevent it from creating
orphan lines.
This PR also sets a minimum idealLineWidth for prettifyRange() which is based
on the size of the longest inline item to be prettified. When this minimum is
not met, we fall back to using greedy text wrapping.
