Remove CodeQL from CI

[ValarDragon]

What is the purpose of the change

Removes CodeQL. It takes forever, and I'm unconvinced its adding anything of value. We should just get Informal's gosec fixed, and use that imo.

If folks feel like CodeQL is useful, we can investigate speedup strategies in #1578 , but atm I'm not sure its helping us any.
