I had a short call with @romeroalx and we discussed moving more logic into tasks.py in a way that completely abstract build system internals from the user and from Github workflows.

Awesome! This is fine by me to get merged for now.
Once we merge the --enable-systemd flag for meson you can fix that TODO and merge this PR.

One thing that irks me (but we shouldn't do anything about it just yet) is the use of environment variables. I think in the long term we want to move to being very explicit about everything we pass, so using invoke parameters would be better, and we can get rid of weird stuff like echo SANITIZERS=... >> $GITHUB_ENV.

The systemd configure flag is added here: #14055

The systemd configure flag is added here: #14055

That was merged. So this PR can now be merged after the systemd configure flag is enabled on meson.
