### 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

[Shader dependency.zip](https://github.com/godotengine/godot/files/11547654/Shader.dependency.zip)
uncomment include, and the editor will freeze and crash

		set_error(RTR("Unmatched endif."), line);
		return;

	if (state->previous_region != nullptr) {
		state->previous_region->to_line = line - 1;
		state->previous_region = state->previous_region->parent;
	}
	if (!p_tokenizer->consume_empty_line()) {
		set_error(RTR("Invalid endif."), line);
	}
	state->current_branch = state->current_branch->parent;
	state->branches.pop_back();
