Make ftgrays compile with _STANDALONE_ and FT_STATIC_RASTER again.

Problems reported by suyu@cooee.cn.

* src/smooth/ftgrays.c (FT_DEFINE_OUTLINE_FUNCS,
FT_DEFINE_RASTER_FUNCS) [_STANDALONE_]: Define.
[!_STANDALONE_]: Include ftspic.h only here.
(ras): Define/declare after definition of `TWorker'.
Use `RAS_VAR_' where necessary.
