[arch-dev-public] Removing dependency on fontconfig/xorg-mkfontscale of font packages

We received a Feature Request today to remove fontconfig and xorg-mkfontscale dependencies from our font packages according to our own font packaging guidelines [0]. I discussed with Eli on #archlinux-bugs and we think it's a no-brainer but before creating a TODO we'd like to ask for your opinions first. Thank you [0] https://bugs.archlinux.org/task/66012
