### 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

	if (index < code.size()) {

	return 0;

	while (index < code.size()) {
		char32_t c = code[index++];

			stripped.push_back('\n');

		if (c == p_what) {
			return true;
