Allow using old ender pearl behavior & apply ender pearl exploit patch (#11524)

Browse source 
When enabled, ender pearls will not load chunks and will save to the world instead of the player.

Also changes the exploit config to be default false, as it only makes sense when legacy behavior is enabled.
