Improve the path select GUI (#5852)

- Allow lua to chose whatever directories or files can be selected - Fix selecting directories - Rename dialog to `guiPathSelectMenu` from `guiFileSelectMenu` - Rename lua function for opening the menu from `show_file_open_dialog` to `show_path_select_dialog` - Remove duplicate code and fix code style. Related changes - fix `clang-format` whitelist. - Regenerate minetest.conf.example
