tests: Stop bundling "perf" tests with gnome-shell
Now that scripts are loaded as external modules, there's no reason anymore for bundling them with the gnome-shell executable. Just move the scripts into a dedicated folder in tests/ and run them from there. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2812>
