REGRESSION(312179@main):

Reviewed by Alan Baradlay and Zak Ridouh.
https://commits.webkit.org/312179@main made
FontCascade::glyphDataForCharacter's mirror a no-op
when HAVE(CORE_TEXT_BIDI_MIRRORING) is enabled, on the assumption that all
callers eventually pass
through CTFontShapeGlyphs which would mirror at shape time. However, that's not
always true. For
example, MathML's MathOperator violates that assumption: it calls
glyphDataForCharacter with
mirror=true and then paints the resulting glyph directly via
GraphicsContext::drawGlyphs, never
invoking the CoreText shaper.
