AX: AccessibilityRenderObject::textRuns can get all character widths at once
https://bugs.webkit.org/show_bug.cgi?id=292905
rdar://151198015
Reviewed by Joshua Hoffman.
FontCascade::widthForCharacterInRun has a lot of overhead, so calling it in a
loop to
get each character width is inefficient. Instead, do what FontCascade does and
use the proper iterator to fill a GlyphBuffer for the whole text run at once.
Then, the width of each glyph and its corresponding character index can be
retrieved from the GlyphBuffer in a simple loop.
