fix(vehicle): fix repair not working after going in water

[xiaoxiao921]

Closes #2995

It's a bandaid fix but it works, there are multiple issues though. First person can't be used anymore in that specific vehicle, and can't be rentered. I tried messing with the vehicle flags and physical flags without any success sadly.

I exclusively play in FPV, this fix is not acceptable to me as the original ticket submitter.

Tested and working, but...

@xiaoxiao921 nailed it with the 0xD8 offset. Well done.
private int _oVState = 0xD8; // int 0:Player 1:NPC 2:Unused 3:Destroyed

Don't need anything else after that besides VEHICLE::SET_VEHICLE_FIXED(veh)

I think this concept could be easily expanded to repairs from any sort of destructive event such as explosions. Would be handy since a lot of mod menus can just explode your vehicle, and not everyone likes playing with godmode.

If vehicle repair can be refactored to remember the player's last vehicle (like we can with GET_VEHICLE_PED_IS_IN(ped, lastVehicle = true), then the vehicle could be repaired even without the player having to physically be inside it. The bitmask could probably work for that case as well to recover the vehicle from any destroyed state, including a smouldering heap.

Then repair_engine_from_water could be renamed as something like repair_destroyed_vehicle. Would be great to be able to quickly repair a vehicle that was destroyed via explosion griefing without having to recall it from the PV list or call Mors.
