Core/Scripts/DB: remove hardcoded text from 'npc_disciple_of_naralex'

- moved 2 #define text lines to enum, already in npc_text
- new gossip_menu_option for NPC 3678 Disciple of Naralex
- using `ADD_GOSSIP_ITEM_DB` instead of `ADD_GOSSIP_ITEM`

Tested on both alliance and horde characters, works just like before.

(cherry picked from commit bc03fed)
