Reviewed by Jer Noble.
Auto-generated subtitles use the 708 caption code path, which is always
non-wrapping. This patch adopts new Core Media SPI
kCMTextMarkupAttribute_PreventLineWrapping. When the attribute's value is
true, we continue setting text-wrap:nowrap on the vtt cue. When the attribute's
value is false, we set text-wrap:wrap.
No new tests.
