Converts a bunch of time/delay vars to use time defines (#92495)

## About The Pull Request

Converts as many time vars expressed in deciseconds as I could find to
use time defines.

## Why It's Good For The Game

Makes these values neater and more readable.

## Changelog
🆑
code: Converted a lot of time-based variables to be expressed with time
defines.
