these can be trivially hardcoded as static / constexpr arrays of path suffixes, we do that everywhere else.

This changeset replaces the statically declared icon theme paths with a list built by inspecting the XDG Data directories,
XDG_DATA_DIRSandXDG_DATA_HOME, for icons and defaulting to/usr/local/share/iconsand/usr/share/iconsif the relevant XDG environment variables are undeclared. It will also search for icons in the non-XDG compliant~/.iconsdirectory to preserve existing function.The motivation for this change is to allow
hyprtoolkitto search for icon themes in non-FHS compliant distributions (e.g. NixOS) more easily. For example, NixOS does not use/usr/shareor/usr/local/sharedirectories. Instead, it setsXDG_DATA_DIRSto include/run/current-system/sw/share. I wrote this so I didn't have to wrap the existing nix derivation in abuildFHSEnvor author a patch.
