Cyborgs can now choose what type of brain they spawn with.

[BiancaWilkson]

What Does This PR Do

This PR adds a new section to character creation, allowing players to choose whether their borg will spawn in with an MMI, a robobrain, or with a positronic brain. It also adds a new column to the SQL database for storing this info. Fixes #23582

Why It's Good For The Game

It adds more options for character customization for a role that is already very difficult to customize a character for.

Testing

Spawned in with all different types of borg, and gibbed them to make sure the brains were correct. I don't have SQL database set up myself, so I was unfortunately not able to test if the queries work properly. Advice is appreciated.
