Refactoring hell is here again!

Before I start on syscalls for the userspace binary, I’ve decided to first get most TODOs done, like updating the safety comments and rustdoc, refactoring the ELF loading stuff to properly utilize KSTATE::procs, proper error delegation and more.

I’ve finally finished refactoring the TSS, GDT and IDT properly by removing the struct wrapper for GDT and IDT, getting rid of all the Onces and more. Additionally, I refactored KSTATE::cpu to be an arch-independent container of arch-specific structs.

holy crap ive got so much left to refactor… and the new bodycam update just came out i wanna play but am stuck doing kernel stuff and some other stuff :’)
