(FINAL 1.16.2) Improve Entity Activation Range passenger behavior
Previously, Entity Activation Range only applied to the root entity of a vehicle chain.
If that vehicle is active, every entity as it's passenger would then tick.

This creates scenarios where EAR does not apply your desired ranges to passengers.
Additionally, any entity that was a passenger never had its inactiveTick method called
when the parent was inactive, creating behavioral desyncs.

This could of been a source of many villager issues when those villagers were in minecarts
as players commonly do.

Now we will process passengers checking their activation state independently of their vehicle
and if they are inactive, call their inactiveTick() method to ensure state remains consistent.

This also helps improve any desync issues with entity position of passengers too.

This also removes immunity for passenger/vehicles, so it should improve performance
of these minecart villagers too for EAR.
