[harfbuzz] Fix vertical text layout
[harfbuzz] Fix vertical text layout

"Fixed" in the sense that it works exactly like the non-HarfBuzz case,
but that is already a bit broken. Need to get rid if the little OpenType
layout engine in ServerFont::ApplyGSUB() and use HarfBuzz's vertical
text layout capabilities.
