[autofit] Use `global' HarfBuzz font object. 

We now use `hb_font' instead of `hb_face' since yet-to-come changes
need this.

* src/autofit/afglobal.h: Include `hbshim.h'.
(AF_FaceGlobalsRec) [FT_CONFIG_OPTION_USE_HARFBUZZ]: New member
`hb_font'.

* src/autofit/afglobal.c (af_face_globals_new)
[FT_CONFIG_OPTION_USE_HARFBUZZ]: Create `hb_font'.
(af_face_globals_free) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Destroy
`hb_font'.

* src/autofit/hbshim.h: Include HarfBuzz headers.

* src/autofit/hbshim.c: Include `hbshim.h' instead of HarfBuzz
headers.
(af_get_coverage): Updated.
