Code cleanup: Sorting (#83017)

## About The Pull Request
1. Removes code duplication 
2. Fully documents `sortTim()`
3. Makes a define with default sortTim behavior, straight and to the
point for 95% of cases
4. Migrates other sorts into the same file
5. Removes some redundancy where they're reassigning a variable using an
in place sorter

For the record, we only use timSort
## Why It's Good For The Game
More documentation, easier to read, uses `length` over `len`, etc
Should be no gameplay effect at all
