[autofit] Use macros for (unsigned) flags, not enumerations.

Browse Source 
This harmonizes with other code in FreeType (and reduces the number
of necessary casts to avoid compiler warnings).

* src/autofit/afblue.hin: Make flag macros unsigned.
* src/autofit/afblue.h: Regenerated.

* src/autofit/afcjk.h: Replace flag enumeration with macros.
* src/autofit/afcjk.c: Updated.

* src/autofit/afhints.h (AF_Flags, AF_Edge_Flags): Replace with
macros.
* src/autofit/afhints.c: Updated.

* src/autofit/aflatin.h: Replace flag enumerations with macros.
* src/autofit/aflatin.c, src/autofit/aflatin2.c: Updated.

* src/autofit/aftypes.h (AF_ScalerFlags): Replace with macros.
