Build godot-runner/export template

Description

Other distros such as openSUSE or fedora build a godot-runner which is basically just the export template (with build args target=template_release).
This is useful because first this is a simple binary that you can provide a pck file via the --main-pack argument and run a game/app and second it would make packaging easier because it makes it possible to require it for building and then use it as a export template instead of downloading the export template from online sources.
Would it be possible to add this to archlinux as well?
