By simulating the exact processing that Java Edition does on the client-side, we can achieve full packet parity with Java when interacting with an entity.
* Prevent boats from floating when a Bedrock player rides in the back
* Update llama and shulker mount height offset
* Fix Trader llama mount offset
* Change passengers to an IntList
Also move rotation lock stuff to EntityUtils
* Allow EntityCache.getEntityByJavaId to return the session's player
Removes many checks from several translators.
* Fix mount offset on armorstands and area effect clouds
Also prevent area effect clouds from despawning when used as an invisible entity (used in GSit to offset players riding on other players)
* Update mount offsets on height changes
TODO test this
* Actually update vehicleId and optimize StriderEntity metadata update
* Don't hide marker armor stands and properly update mount offsets
* What?
* Remove y offset for Shulkers riding other entities
* Confirm teleports in the order received
This allows Bedrock players to move after standing up when using GSit
* Fix mount offset for riders on baby zoglins
* Cache only the latest teleport and confirm teleports immediately
* Fix crawling with GSit
* Inline var and undo respawn method
* Use Entity reference for vehicles
* Remove ridingVehicleEntity from GeyserSession
* Use Entity references for passengers and drop cachedPlayerEntityLinks
* Reuse variable and remove setVehicle(null)
