AppImage Support

[e-dong]

App Images are Linux distro agnostic binaries, so this would be great to prioritize for Linux support

Also add a job that builds a pacman binary (to be used with Arch linux).

Both of these new binaries should be artifacts to be used during release (see comment below).

Can reference how the Windows release job is done: https://github.com/Proryanator/encoder-benchmark/blob/main/.github/workflows/windows_release.yml

Would be similar in the same way that it takes an input name/tag (set during the release github action), and passes the binaries as artifacts.
