Oops. I broken this badly and the test suite did not notice. That

[OT] Use general-category, not GDEF class, to decide to zero mark advances
...
At this point, the GDEF glyph synthesis looks pointless. Not that I
have many fonts without GDEF lying around.
As for mark advance zeroing when GPOS not available, that also is being
replaced by proper fallback mark positioning soon.

[GSUB] Wire the font, not just the face, down to substitute()
...
We need the font for glyph lookup during GSUB pauses in Indic shaper.
Could perhaps be avoided, but at this point, we don't mean to support
separate substitute()/position() entry points (anymore), so there is
no point in not providing the font to GSUB.
