Scripts/Naxxramas: Faerlina cleanup:

- Move greeting to areatrigger instead of MoveInLineOfSight hack
- Clean up add spawn handling to prevent various glitching with combinations of evade state and add aggro
- Ensure all adds are always pulled alongside the boss and vice versa
- Add missing texts.
- Fix a bug in the core that prevents castable-while-dead spells (such as Widow's Embrace) from appearing on possess bars.
