Nicola Papale ffa489a846 Ignore Timeout errors on Linux AMD & Intel (#5957)
# Objective

- Fix #3606
- Fix #4579
- Fix #3380

## Solution

When running on a Linux machine with some AMD or Intel device, when calling
`surface.get_current_texture()`, ignore `wgpu::SurfaceError::Timeout` errors.


## Alternative

An alternative solution found in the `wgpu` examples is:

```rust
let frame = surface
    .get_current_texture()
    .or_else(|_| {
        render_device.configure_surface(surface, &swap_chain_descriptor);
        surface.get_current_texture()
    })
    .expect("Error reconfiguring surface");
window.swap_chain_texture = Some(TextureView::from(frame));
```

See: <94ce76391b/wgpu/examples/framework.rs (L362-L370)>

Veloren [handles the Timeout error the way this PR proposes to handle it](https://github.com/gfx-rs/wgpu/issues/1218#issuecomment-1092056971).

The reason I went with this PR's solution is that `configure_surface` seems to be quite an expensive operation, and it would run every frame with the wgpu framework solution, despite the fact it works perfectly fine without `configure_surface`.

I know this looks super hacky with the linux-specific line and the AMD check, but my understanding is that the `Timeout` occurrence is specific to a quirk of some AMD drivers on linux, and if otherwise met should be considered a bug.
