Adds vehicles and mechs

[kyres1]

Adds the basics for the following vehicles :

1. Ports the Flail and Broadsword from Monolith Mecha Update Monolith-Station/Monolith#1151
2. Adds the Starlight mech
3. Adds the Striker IFV
4. Adds the Hopper spider tank
5. adds the basic necessities to make those work from Monolith

To-do:

• Finish the normal civilian cars
• Bikes, at least one
• Port Mob collisions space-wizards/space-station-14#34580
• Fix attribution which was missing from multiple jsons for some reason

After this PR space-wizards/space-station-14#39646 is a serious consideration. If it's merged to wizden before this is done I will scrap it and re-do it with this ported
