etc: release: Switch to Guile declaration of artifacts.v1.5.0rc1

This is a rewrite of the bash commands for generation of guix binary
tarballs and system images to Guile. I am expecting this will help us
significantly with getting the same derivations locally and from Cuirass,
instead of relying on images/tarball job specifications and trying to tweak
it locally to have the same ones.

Implements: #4347, #4348.

* etc/teams/release/artifacts-manifest.scm: Make a manifest with
release artifacts for all supported systems.
* etc/teams/release/artifacts.scm: Collect artifacts for
all supported systems into a union with proper names for
the release artifacts.
* Makefile.am (release): Use time-machine instead of pre-inst-env; Switch to
building new artifacts.scm
