Correct BWL spawns.

[Daribon]

🍰 Pullrequest

This PR corrects most of the spawns in BWL. Almost entire BWL was previously spawned by hand.
With this PR, almost every single NPC and object has had some change to it. Oroxy helped out with some of the initial work with objects.

Some of the changes:

• No extra custom Blackwing Taskmaster pack in Supression Room.
• No extra custom Death Talon Hatcher patrol in Supression Room.
• Suppression Room is no longer using custom waypoints. Entire room has been respawned to use is_spawn.
• Death Talon pack after Vaelstrasza is now semi-random. One Captain per pack, but all of the NPCs can spawn at any spot.
• Death Talon pack in the lab is now semi-random. One Wyrmguard per pack, but all of the NPCs can spawn at any spot.
• Many other small changes.

Proof

• From sniff.

Issues

• partly fixes Instance: Blackwing Lair (WIP) #369

How2Test

• .tele bwl

Todo / Checklist

• Add spells to Blackwing Spellbinder, make their waypoints more correct.
• Small cleanup
• Figure out why Death Talon Wrymguard spawns in same spot when grouped in creature_groups_entry_limit.
• Investigate Blackwing Technician irregularities between different sniffs.

Fixed SQL errors and added correct grouping for the entire raid.

Ready for merge.
