DB/SAI: Misc Fixes from IT

By @dr-j and @untaught
Fixes #11081 fixes #11080 fixes #11082
Core/Quest: Remove assertion

Remove assertion about Quest ExclusiveGroup since they are triggered even when adding valid quests to npcs. Fixes #8336 .
How to reproduce steps:
- .gm off
- add quest 11335 in creature_queststarter
- .reload creature_queststarter
- get in range of that creature
- .gm on
- assertion triggered
Core/SAI: Rename SMART_EVENT_TARGET_CASTING to SMART_EVENT_VICTIM_CASTING as that's what it actually does. It was often confused to use the target_type field instead of the victim.
Core/Transports: Fixed players taking fall damage when teleporting from transports

Closes #11076
Core/Auras: Added serverside checking for UNIT_FLAG_PACIFIED when attempting to start melee attack

Closes #8623
