Add function `ft_property_string_set'. 

This is a preparation for handling an `FREETYPE_PROPERTIES'
environment variable to control (some) driver properties.

No change in functionality.

* src/base/ftobjs.c (ft_property_do): Add `value_is_string'
parameter.
(ft_property_string_set): New function.
(FT_Property_Set, FT_Property_Get): Updated.

* include/freetype/internal/ftobjs.h: Updated.

* include/freetype/internal/services/svprop.h
(FT_Properties_SetFunc): Add `value_is_string' parameter.

* src/autofit/afmodule.c (af_property_set), src/cff/cffdrivr.c
(cff_property_set), src/truetype/ttdriver.c (tt_property_set):
Updated, emitting an error currently if `value_is_string' is set.
