Close #25037
Close #31037

This PR adds a Arch package registry usable with pacman.

![grafik](https://github.com/user-attachments/assets/81cdb0c2-02f9-4733-bee2-e48af6b45224)

Rewrite of #25396 and #31037. You can follow [this
tutorial](https://wiki.archlinux.org/title/Creating_packages) to build a
package for testing.
