CSG with collision is not baked in NavigationRegion3D with "Static Colliders" as geometry type

Windows10, AMD Ryzen 9 5900X, NVIDIA GeForce RTX 3060 Ti, driver version 30.0.15.1179, compatibility.

Issue description

When having a CSG based environment, navigation region 3d cannot use static colliders as geometry type. This limits the use of CSG I think.
I would love to be able to have CSGs with different collision layers and some to be baked into the nav region and others not.

Steps to reproduce

1. Add a NavigationRegion3D to a scene
2. Add a CSG box of 5, 1, 5m, enable collision
3. Bake the nav region with geometry type set to static colliders
4. See that nothing was baked.

Minimal reproduction project

Trivial to reproduce

StaticBodies and their collision shapes for CSG nodes are created using low-level PhysicsServer functions as opposed to StaticBody/CollisionShape nodes: https://github.com/DarioSamo/godot/blob/e3c4fa2455dc8c42da4c7485d48d5af50a76cdfe/modules/csg/csg_shape.cpp#L35-L64

This likely impacts the navigation bake step if it doesn't look for those PhysicsServer-created bodies/shapes.

Duplicate of #79843 already fixed in master with #79643.

When parsing static colliders it now checks both the csg use_collision property and if there is a match with the csg collision_layers.
