[autofit] Improve tracing messages.
* src/autofit/afcjk.c (af_cjk_metrics_init_widths): Mention script ID in tracing message. (af_cjk_metrics_init_blues): Initialize `axis' outside of the inner loop. Improve tracing messages. (af_cjk_hint_edges) [FT_DEBUG_LEVEL_TRACE]: New variable `num_actions' to count hinting actions. Improve tracing messages. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Mention script ID in tracing message. (af_latin_metrics_init_blues, af_latin_hint_edges): Improve tracing messages.
