Entities/Unit: Nuke Map::ForceRespawn from orbit, with the following implications:

- .npc respawn no longer causes stupid things to happen (Fixes #23014)
- ::DeleteFromDB methods on Creature and GameObject rewritten to be as sensible as such a colossally stupid method can ever be. They're static now.
- .npc delete and .gobj delete ported to new argument handling, and rewritten as per above. They can no longer crash the server when used in instances, too. Yay for that.
- Adjusted various dusty cobwebbed hacks around the core (why does waypoint visualization use permanent spawns *shudder*) to still work too.
