Core/Misc: A variety of clean-up changes, mostly following up on 532ab1c to fix legacy bugs exposed by it:

- Triggers can no longer have a threat list (this may expose some ugliness in old legacy scripts)
- Threat entries are forced to OFFLINE if the AI refuses to attack the target
- Clean up passive creature evade behavior to be more consistent
- Fix a months old issue in spawn group management that would cause "Inactive" to incorrectly show in .list respawns for system groups outside of map 0
- Valithria script cleanups, remove old hacks and make it work with the new system. Closes #21174.
- Some strings cleanup

(cherry picked from commit 9f9507e6a1fd50a5ce643a4096c1712700244a61)
