Crash with WGSL `textureLoad` from depth textures is not supported in GLSL

some information about wgpu is available in https://github.com/gfx-rs/wgpu/issues/8272

Examples from the Bevy repo run as expected.

## Bevy version and features
0.16.1

## \[Optional\] Relevant system information

Arch Linux
Rustc 1.88.0

## What you did

```
use bevy::prelude::*;

fn main() {
App::new().add_plugins(DefaultPlugins).run();
}
```

`cargo run`

## What went wrong

Compilation is successful. The window crashes as soon as it launches, with this message:

```

Reproduce the crash with the minimal Bevy application using `cargo run` on the reported Arch Linux setup, then inspect the `bevy_render::renderer` and `bevy_render::render_resource::pipeline_cache` errors around `create_compute_pipeline`. Done means the depth downsample compute pipeline no longer crashes during startup on the affected OpenGL/GLSL backend; the report points to wgpu for the translation failure.
