[WebCore] Optimize text layout building
https://bugs.webkit.org/show_bug.cgi?id=273301
rdar://127095998
Reviewed by Alan Baradlay.
This does micro-optimizations for Text Layout.
1. TextUtil::containsStrongDirectionalityText should use StringView::codePoints.
2. FontCascade::characterRangeCodePath should first take size and data from
span.
3. TextOnlySimpleLineBuilder should take rootStyle and threading it through
line building code.
4. InlineItemsBuilder should appropriately expand the Vector capacity before
appending items in loop.
