[Quest] Kodo Roundup

by @pete318, closes #12811

Fixes the remaining bugs in the "Kodo Roundup" quest in Desolace:
- removes combat status from creature 11627, Tamed Kodo
- sets normal walking speed as the creature's follow speed
- makes the Tamed Kodo stop at Scrabblescrew's Camp
- enables quest objective count 0/5 -> 5/5, quest complete
- SQL (by @tkrokli) links the missing gossip text in the DB

(cherry picked from commit 1c8486e1a8)
