UB: `CTFontGetVerticalTranslationsForGlyphs` does not take `CTFontOrientation`

[madsmtm]

Unlike the other CTFontGet*ForGlyphs methods, CTFontGetVerticalTranslationsForGlyphs does not take CTFontOrientation, see Apple's docs.

This means that calling CTFont::get_vertical_translations_for_glyphs is immediate UB (the calling convention is wrong).

Disassembling, it seems that CTFontGetVerticalTranslationsForGlyphs actually contains a "workaround" for this, by testing whether the third argument is 1, and if it is, it simply returns immediately.
