Moves lua off of the timer subsystem and onto its own internal scheduler. (#82131)

## About The Pull Request
Lua uses the timer subsystem, which can end up holding the entire timer
subsystem if lua is creating a lot of timers.
The solution to this is to use an internal scheduler instead so that the
load gets placed onto the lua subsystem.

## Why It's Good For The Game
Performance improvement when using lua scripts.

## Changelog
🆑
refactor: Auxlua no longer uses the timer subsystem to get stuff done,
lua scripts shouldn't slow down timers anymore.
