Fall detector detects drops through walls

[BrailleBennett]

The fall detector makes a warning noise for falls/drops, even if they are obscured through walls. This is most noticeable when you get an end spawn that is under the main island and surrounded by end stone. There is no way the player can actually fall here, but yet the fall detector still triggers because there is a drop outside of the spawn box.

Won't be able to resolve unless implement a path finding solution or use existing zombie/villager path finding logic
