Add enum for tatl hint id

[jpburnett]

This commit adds the enum TatlHintId for helping with documenting what this->actor.hintId does. It is similar to what OoT does with the naviEnemyId.

This doesn't build because Elfbub uses TATL_HINT_ID_SHABOM instead of TATL_HINT_ID_IGOS_DU_IKANA. It's bizarre that it even uses a hint ID in the first place.
