Added an occlusion culling system with support for static occluder meshes. It can be enabled via `Project Settings > Rendering > Occlusion Culling > Use Occlusion Culling`. Occluders are defined via the new `Occluder3D` resource and instanced using the new `OccluderInstance3D` node. The occluders can also be automatically baked from a scene using the built-in editor plugin.
