### Godot version

4.0.1(flatpak)

### System information

Linux openSUSE

### Issue description

Cyclic Dependencies in shader result in infinite loop

### Steps to reproduce

Create 'main' shader that includes other shader, let's say `inc_me1` and `inc_me2` if 'inc_me1' that includes 'main' shader and 'inc_me2' includes 'inc_me1'. It results in a freeze.

### Minimal reproduction project

uncomment include, and the editor will freeze and crash
