[truetype] Store and use design coordinates also. 

* include/freetype/internal/services/svmm.h (FT_Get_Var_Blend_Func):
Add `normalizedcoords' argument.

* src/truetype/ttgxvar.h (GX_BlendRec): Add `coords' field to store
the design coordinates of the current instance.
Updated.

* src/truetype/ttgxvar.c (TT_Set_MM_Blend): Move functionality to...
(tt_set_mm_blend): ... New function.
Convert data in `normalizedcoords' array to `coords' array on
demand.
(TT_Set_Var_Design): Store argument data in `coords' array.
(TT_Get_Var_Design): Get data from `coords' array.
(tt_get_var_blend): Updated.
(tt_done_blend): Updated.

* src/cff/cffload.c, src/cff/cffload.h (cff_get_var_blend): Updated.

* src/cff/cf2ft.c (cf2_getNormalizedVector): Updated.

* src/cff/cffobjs.c (cff_face_init): Updated.
