Standerdizing currency symbols (Part 1?) (#94128)

## About The Pull Request
Passes a standardized define into some of the tgui to parody behavior
with vending machines.
Adds a few defines for money symbols to make it easier to rework types
of money.

If yall are for this I can also go through and find and replace a ton of
strings and other tgui with these, but dont want to sink 2 much time
into it if not.
