Jason Penilla ec53bd41e7 Allow using old ender pearl behavior & apply ender pearl exploit patch (#11524)
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.
