### Godot version

4.0 beta (e1648b3327431a09cc9498663fac483275eb711d)

### System information

Mageia 9, Linux

### Issue description

When exporting a project with no attached script (or with only a builtin GDScript), the following error is printed:
```
ERROR: Can't open file from path 'res://.godot/global_script_class_cache.cfg'.
   at: get_file_as_bytes (core/io/file_access.cpp:699)
```

And while the export succeeds, when running the project, it prints:
```
ERROR: Couldn't find the given section "" and key "list", and no default was given.
   at: get_value (core/io/config_file.cpp:86)
```

We should ensure that this file is always created, regardless of whether there are scripts to parse for class names or not. It should always contain at least `list=[]`.

### Steps to reproduce

- Create new project
- Create main scene with no script
- Export

### Minimal reproduction project
