CI/AppImage: Make anylinux appimage

[Samueru-sama]

Uses this appimagetool which has a deploy everything mode that bundles glibc in the appimage that makes the appimage be able to run in any distro, be it very old distros or even musl distros. It also uses a static runtime which prevents the no libfuse2 issues in newer distros.

Note that I'm not replacing the existing appimage made with linuxdeploy, I'm adding an extra one, because go-appimage doesn't support the same arguments as linuxdeploy and also because there is a regression that the new appimage runtime has a hardcoded path to /usr/bin/fusermount* which means that some distros that keep /bin and /usr/bin separated might have trouble launching the appimage unless fusermount is symlinked to /usr/bin or the FUSERMOUNT_PROG env variable is set.

Fixes #11103

Update: Now glibc and all the dependencies are bundled manually instead.

Alright why doesn't the wildcard expand? 😅

I made sure that the wildcard wasn't in quotes but I still got mv: cannot stat 'helix-*-x86_64.AppImage.AppImage': No such file or directory errors.

I did that because the $VERSION var gets changed when making the second appimage.

Edit: I just did a crude test on my pc using dummy files and mv "$APP"-*-"$ARCH".AppImage works there without problems 🤔

Edit2: LOL nvm

Is there any update on the commits submitted by @Samueru-sama? Really wanting to make use of this on Chimera-Linux and EasyOS and have thus been waiting patiently.
