#[derive(ShaderType)] triggers compiler warning

## Bevy version

0.16.1

## What you did

```rust
#[derive(ShaderType, PartialEq, Clone, Copy)]
struct ShaderInputType {
position: Vec2,
factor: F32,
}
```

## What went wrong

Compiler warning
```
warning: function `check` is never used
```

## Additional information

`cargo expand` shows that the macro generates a `check` function, but it's not used and might be missing a `#[allow(dead_code)]` attribute or something like that.
