verb macro system (pr 1/3) (#96720)

## About The Pull Request

just macro-izes all the usages of verbs in the codebase as a
pre-requisite to my follow up pr that serializes all the verbs arguments
so we can tgui-ify the command bar, so we can then put it on the
onscreen map.

this also basically does the same as #94487 so can easily be integrated
into the verb queueing stuff... but does not actually do any verb
queueing by itself. basically im just trying to be

## Why It's Good For The Game
it doesn't really do anything by itself but it does let us do more stuff

## Changelog
