fix(Core/Loot): (#7452)

- Players that did not participate in killing dungeon boss are not eligible to get loot.
- Players that are too far away from the looted object are not eligible to get loot.
- Players that released spirit and were outside the dungeon when the loot has been released are eligible to get loot.
- Players that have pending bind are not eligible to get loot.
- Properly get loot recipient for some chests in dungeons.
- All above fixes should work in any loot mode (group loot, master loot, etc.)
- Closes #2104.
