### Godot version

v4.0.2.stable.official [7a0977ce2]

### System information

GNU/Linux, GLES3 & Vulkan, Intel UHD 770

### Issue description

When passing arrays of color objects to the shader, the shader program cannot get the values, even when converted to vector arrays.

And source_color hint does not convert colors correctly when passed through an array.

```
var colors := [
	Color.hex(0x0088ffff),
	Color.hex(0xff000088),
	Color.hex(0x00ff0000),
	Color.hex(0x0000ffff),
]
func _ready() -> void:
	var shader: ShaderMaterial = mesh.material
	shader.set_shader_parameter("vec4_no_hint", colors)
	shader.set_shader_parameter("vec4_hint", colors)
	shader.set_shader_parameter("vec3_no_hint", colors)
	shader.set_shader_parameter("vec3_hint", colors)
	var cvt_colors = colors.map(func (c): return Vector4(c.r, c.g, c.b, c.a))
	shader.set_shader_parameter("cvt_vec4_no_hint", cvt_colors)
	shader.set_shader_parameter("cvt_vec4_hint", cvt_colors)
	shader.set_shader_parameter("cvt_vec3_no_hint", cvt_colors)
	shader.set_shader_parameter("cvt_vec3_hint", cvt_colors)
```

Result With GLES3:
