[IFC][Partial layout] Populate InlineDamage::m_trailingDisplayBoxes for
subsequent partial layout when new renderer is added/removed.

<rdar://problem/106901404>
Reviewed by Antti Koivisto.
Let's hold on to the line ending display boxes so that
InlineFormattingContext::lineLayout can match them with the freshly laid out
lines. This is to figure out whether damage stops at a given line.
(Slightly refactor candidateLineIndex to return optional<size_t> to be able to
fallback to full layout when we can't find a valid line index -unexpected state
case).
Note that this is not enabled yet when InlineTextBox's content is being mutated.
