use ssr dynamic offset in volumetric fog bind group (#13544)

# Objective

- #13418 broke volumetric fog

```
wgpu error: Validation Error

Caused by:
    In a RenderPass
      note: encoder = `<CommandBuffer-(2, 4, Metal)>`
    In a set_bind_group command
      note: bind group = `mesh_view_bind_group`
    Bind group 0 expects 5 dynamic offsets. However 4 dynamic offsets were provided.
```

## Solution

- add ssr offset to volumetric fog bind group
