[bug#61243] Add WASM-4 fantasy console and prerequisites

[Thompson, David]

Hello all,

This set of 4 patches adds WASM-4 (https://wasm4.org/), a fantasy
console that runs game "cartridges" compiled to WebAssembly.  It's a
fun way to learn about WebAssembly using a relatively simple system.
I've seen a WASM-4 game that was assembled using Racket, which I
thought was pretty neat.  It would be even cooler if someone did
something like that with Guile!

Packaging this thing was not exactly straightforward due to dependency
bundling via git submodules, but I was able to unbundle everything.
