Vehicle Create Admin Permission

PlotSquared Feature Suggestion:
Adding a permission like plots.admin.vehicle.other to allow vehicles to be placed on other plots (and roads)

How should it be implemented?
In the VehicleCreateEvent don't remove the vehicle, "if the permission is set".
The problem is that the VehicleCreateEvent cannot return the player placing it, specifically because things like Dispensers/Droppers can also place Vehicles.
This means we'd need to capture PlayerInteractEvents or PlayerBlockPlace Events and flag vehicles there (e.g. the vehicle has a unique id, this could be added into a hashmap which is then compared against in the VehicleCreateEvent).

Additional context

Checklist:

• I made sure there are no duplicates of my suggestion (Use search)
• I made sure my suggestion does not exist yet (Check the wiki)
• I made sure my suggestion is useful for the majority of PlotSquared users

I'm not 100% sure about the third check, it's mostly for "fun" (e.g. riding a minecart on users roller coasters), but it's not like having a negative impact on anyone etc

Edit: I think my analysis was wrong, shouldn't vehicle creates be covered by interact.other permissions already?

Start by tracing VehicleCreateEvent handling and the existing interact.other permission behavior. Review PlayerInteractEvents and PlayerBlockPlaceEvents to determine how a vehicle's placer could be associated with the creation event, including dispenser and dropper cases. Done means the proposed permission behavior is defined and covered for vehicles on other plots and roads without breaking existing protection.
