### Issue description

I am implementing 3d simplex noise in a spatial shader using this implementation https://github.com/ashima/webgl-noise/blob/master/src/noise3Dgrad.glsl

In shadertoy the implementation produces the expected result:
![image](https://github.com/godotengine/godot/assets/43307034/035c5c16-ecae-45eb-99b9-b77edd881b7e)

But using almost identical code in a Godot shader (only modified to give functions unique names since Godot doesn't support shader function overloading) produces an incorrect result with splotches of the noise falling well outside the [-1, 1] range it is suppose to be in, some even falling outside [-10, 10]:

Stepping through the shader code in shadertoy and Godot, the values begin to diverge at the line
```
  vec4 p = permute( permute( permute( 
             i.z + vec4(0.0, i1.z, i2.z, 1.0 ))
           + i.y + vec4(0.0, i1.y, i2.y, 1.0 )) 
           + i.x + vec4(0.0, i1.x, i2.x, 1.0 ));
```

### Steps to reproduce

Create a new 3D scene, add a MeshInstance3D node as a child of the root. Give mesh instance node a new PlaneMesh (or any other mesh) and under Surface Material Override, add a new material by selecting New ShaderMaterial.
Open the text editor of the shader material and paste the following shader:
```
shader_type spatial;
