CollisionShape3D.debug_fill has much Z-fighting

[azur-wolve]

Tested versions

4.4-stable

System information

Debian 12 (X11), Godot 4.4-stable, Vulkan (Forward+), RTX 3060

Issue description

The new debug shape colors #90644 paired with "fill" has z-fighting.
Thats bad for level geometry.

CollisionShape.debug_fill is enabled by default.

The problem is that z-fighting happens when mesh and shape match in space, not sure if there's any solution for that.

For now would be better to disable CollisionShape.debug_fill by default.

Steps to reproduce

Move around geometry with textures and collision shapes to see Z-fighting.

Minimal reproduction project (MRP)

Any with textured geometry and collision.
