[Vertical] fix vertical gpos
...
Wow, it took me a few days to find the right fix!
We now set the advance for attached marks to zero, but we
do this in the _finish() state of gpos, so it shouldn't
regress with fonts like DejaVuSansMono that explicitly
decrease the mark advance width to set it to zero.

Invert the mask logic
...
Before, the mask in the buffer was inverted. That is, a 0 bit meant
feature should be applied and 1 meant not applied, whereas in the
lookups, the logic was positive.
Now both are in sync. When calling hb_buffer_add_glyph() manually,
the mask should be 1 instead of 0.

Fix scale issues
...
hb_font_set_scale() now sets the value to be used to represent a unit
pixel. For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6). For 10px in 16.16 you would set it to
(10 << 16). This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.
