Adds a new station trait Head of Security AI (#3155)

## About The Pull Request
This PR adds a new station trait that does the following
- Disables HoS as a job
- Lowers Security Officer slots from 5 to 2
- Silicons default to Robocop lawset and have access to sec borgs
- Similar to AI law divergency, law boards are removed from the upload
- The AI is barred from antag status at a code level (this does not stop
subversion but it does stop malf)
## Why It's Good For The Game
The problem with security borgs was that they would often follow
spacelaw instead of their actual laws, it was suggested to me that I
make a station trait that puts them on robocop and allows them to pick
the model, this has the benefit of making them not available every
round, but still available sometimes outside of admin bus. Tweaks and
changes for things like how common this trait is can be adjusted in the
future of course!
