Subject: [PATCH] Fix occlusion culling not respecting device limits (#18974)

The occlusion culling plugin checks for a GPU feature by looking at
`RenderAdapter`. This is wrong - it should be checking `RenderDevice`.
See these notes for background:
https://github.com/bevyengine/bevy/discussions/18973

I don't have any evidence that this was causing any bugs, so right now
it's just a precaution.

## Testing

```
cargo run --example occlusion_culling
```

Tested on Win10/Nvidia across Vulkan, WebGL/Chrome, WebGPU/Chrome.
