Admin Subtype of Integrated Circuits (#72303)

## About The Pull Request

Simply adds an admin only subtype of the integrated circuit because I
spawn a lot and this'll save me 30 or so seconds each time I do.
## Why It's Good For The Game

When creating a new admin circuit from scratch being able to skip VVing
it to change the admin_only var would save a bit of time.
## Changelog
🆑
admin: Integrated Circuits now have an admin only subtype, functionally
the same as VVed regular circuits.
