Currently we have an abundance of GTK configuration locations:
- GTK2 gtkrc file
- XSettings config file
- GSettings registry
- Settings.ini file for GTK3 and GTK4
- gtk.css and other stylesheets for injection for GTK3 and GTK4

Each of them have their own complexities. Some of them depend on gtk
version, some do not. Given how different they are, it makes sense to
split them reducing the verbosity of function signatures in the process.
