fix: Overhauls champion titles & codegen champion system (#1430)

## MAJOR CHANGE

Added a champion title system to facilitate the existing champion titles. This should make it easier to extend or create other related game content. Champion titles will be saved in a folder called _ChampionTitles_.

### Motivation

The motivation to refactor was two-folder, but mostly related to performance in two ways.
First, every player had a ChampionTitleInfo object with an array of ChamptionTitleInfo. We want to eliminate the need for this information unless a player actually uses it. This should save a considerable amount of memory.

Second, to facilitate the atrophy mechanic, the champion titles would run atrophy post-world save, adding to the time that the server is frozen. Eliminating this post-world save side effect unlocks our ability to further optimize the world save process since there are no direct side effects.


### Bugs fixed

- [X] Fixed titles getting cut off on the paperdoll
- [X] Fixed champion title not displaying overhead (OPL)
