read-only alist support for VV (#95501)

## About The Pull Request

This adds experimental read-only support for `/alist`s in VV.

I'm not quite sure how to add support for properly changing alists, but
this is better than nothing at least.

## Why It's Good For The Game

Should be able to at least view alists with VV.

## Changelog
🆑
admin: View Variables can now properly view alists, altho it cannot edit
them.
