Fix screenspace_texture example shader compiler error in WebGPU (Browser) (#8682)

Browse Source 
# Objective

Fix the screenspace_texture example not working on the WebGPU examples
page. Currently it fails with the following error in the browser
console:

```
1 error(s) generated while compiling the shader:
:213:9 error: redeclaration of 'uv'
    let uv = coords_to_viewport_uv(position.xy, view.viewport);
        ^^

:211:14 note: 'uv' previously declared here
@location(2) uv: vec2<f32>,
```

## Solution

Rename the shader variable `uv` to `viewport_uv` to prevent variable
redeclaration error.
