[bug#63435] Add vcmi 1.2.1 to games.scm

[Vagrant Cascadian <vagrant@debian.org>]

[-- Attachment #1.1: Type: text/plain, Size: 1089 bytes --]

X-Debbugs-Cc: liliana.prikler@gmail.com, iyzsong@envs.net

The attached patch adds "vcmi", which is in many ways very similar to
the "fheroes2" package, in that it (currently) requires external
non-free assets, but the game engine itself is GPL2. They also both use
assets from the same game lineage (heroes of might and magic).

I struggled to get the tests to work, and they do not seem to be
terribly well maintained upstream. They are even disabled by default by
upstream. I did some very brief manual "testing" that it actually works,
at least!

I had successfully built with various qt*@6 packages, but they are not
currently building; it seems to support qt*@5 too.

Some things failed to build with gcc-11, so I tried gcc-12 and it
worked!

We probably want to try to apply Debian's "privacy-breach" patch to
disable phoning home, as well as the reproducible builds patch and some
additional reproducibility patches I am working on, but figured I would
submit the package to guix for review now, in case anyone else wants to
join me down this rabbit hole...


live well,
