[LFC][IFC] Optimize LineCandidateContent for the most common type of content
https://bugs.webkit.org/show_bug.cgi?id=206371
<rdar://problem/58656853>

Reviewed by Antti Koivisto.

Optimize LineCandidateContent and the caller for the most common type of content (text) and also reduce the RunList vector initial size.
We normally pass one or 2 inline items to the LineBreaker in there.
