Weird Vehicle/Tank/APC roof behavior

[MiniMeatwad]

Description

Related to #15799, a bug where if you move the tank you get shifted even through walls as though you're still on the roof list, you're teleported back to the tank by rotating, and it's fixed by hopping off and back onto the vehicle.

@TiviPlus In case you wanted bugs that are maybe reproducible, and based on anecdote from other TGMC players, rather than nothing.

Test Merges

Irrelevant, probably

Reproduction Steps

Fireman carry a robot on top of the tank roof, they might gain the ability to walk through barricades and vehicles (This happened while on the Alamo and we were taking off), or walk through two vehicles (APC and Tank), or move z-levels on top of the tank and get sent to space.

You can banish the tank and ride it on the side, hop off, and use it to force-displace yourself as you're still on the roof-goer list or something.

You can banish the tank and jump out while it's banished, putting you in space

You can enter the vehicle using a medievac, making you a non-occupant and deletes you when the vehicle breaks.
