[aflatin] Convert adjustment database enum to macros.
We are going to add more values, and we want to use combinations of them.
* src/autofit/afadjust.h (AF_VerticalSeparationAdjustmentType): Replace
with...
(AF_ADJUST_UP, AF_ADJUST_DOWN, AF_ADJUST_NONE): ... new macros.
(AF_AdjustmentDatabaseEntry): Rename field
`vertical_separation_adjustment_type` to `flags`.
* src/autofit/afadjust.c (af_reverse_character_map_new),
src/autofit/aflatin.c
(af_glyph_hints_apply_vertical_separation_adjustments): Updated.
