Optimize SVGTextLayoutAttributesBuilder rotation attribute handling
https://bugs.webkit.org/show_bug.cgi?id=303279
rdar://165585366
Reviewed by Brent Fulgham.
The fillCharacterDataMap() method was using a two-pass approach for
handling rotation attributes: first iterating through explicit rotate
values, then a second loop to propagate the last rotation value to
remaining characters.
This patch optimizes the rotation handling to use a single-pass
approach by leveraging std::min() to automatically select the last
rotation value when the index exceeds the list size.
Also removes the now-unused updateCharacterData() helper function that
was specific to the old two-pass implementation.
