GenerateKDopAsSimpleCollision() clamps vertices that are close to the origin which results in inaccurate primitives

When DOP simplified collision is generated for a mesh that has vertices that are close to the origin, part of the function till clamp any values between -0.5 and 0.5 to be 0.5 which will cause the resulting collision to be formed incorrectly.

1. Download the attached FBXs and import them into a project.
2. Open both of the resulting static meshes in the static mesh editor.
3. On both meshes, select Collision > Add 26-DOP Simplified Collision.
4. Compare the collisions that were generated.
Result: The uebug2 collision does not resemble the mesh or the collision generated for uebug-ok.
Expected: Both collisions should be similar, if not identical.
