### Godot version

63f95c0e58e51ec2939e8b47803cb607fb35cadc

### System information

Windows 11

### Issue description

Using the following code:

```gdscript
extends StaticBody3D

@onready var shape_3d = $CollisionShape3D

func _ready():
	var convex_shape = ConvexPolygonShape3D.new()
	var points = PackedVector3Array()
	
	points.append(Vector3(0, 0, 0))
	points.append(Vector3(1, 0, 0))
	points.append(Vector3(0, 0, 1))
	points.append(Vector3(1, 0, 1))
	
	convex_shape.points = points
	shape_3d.shape = convex_shape
```

produces the correct result:

but generates unnecessary errors:

/*
 * Based on Godot's patched VHACD-version of Bullet's btConvexHullComputer.
 * See /thirdparty/vhacd/btConvexHullComputer.cpp at 64403ddcab9f1dca2408f0a412a22d899708bbb1
 * In turn, based on /src/LinearMath/btConvexHullComputer.cpp in <https://github.com/bulletphysics/bullet3>
 * at 73b217fb07e7e3ce126caeb28ab3c9ddd0718467
 *
 * Changes:
 * - int32_t is consistently used instead of int in some cases
 * - integrated patch db0d6c92927f5a1358b887f2645c11f3014f0e8a from Bullet (CWE-190 integer overflow in btConvexHullComputer)
 * - adapted to Godot's code style
 * - replaced Bullet's types (e.g. vectors) with Godot's
 * - replaced custom Pool implementation with PagedAllocator
