[autofit] While tracing, report script names instead of ID values.

* src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]:
New array.
* src/autofit/afglobal.h: Updated.

* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
af_cjk_hint_edges): Use `af_script_names'.
* src/autofit/aflatin.c (af_latin_metrics_init_widths,
af_latin_hint_edges): Ditto.
