allow(single_component_path_imports) does not apply to imports in annotated modules.

Summary

This might be somewhat similar to some existing issues so if it would be preferable to comment on one of them and close this one that's fine, but I didn't see it specifically.

I have some automatically generated code which triggers the single_component_path_imports lint. I'm not opposed to the lint in general, but I'd rather keep the automatically generated code unedited by hand. I thought I could just add the allow(...) attribute to the module declaration, but it doesn't seem to apply recursively to the code in the declared module.

Reproducer

I tried this code:

#[allow(unused_imports)]
#[allow(clippy::single_component_path_imports)]
mod test {
    use anyhow;
}

I expected to see this happen: The lint would be suppressed.

Instead, this happened: The lint warning continues to appear.

Start by reproducing the annotated-module example and tracing how the single_component_path_imports lint handles module-level allow attributes. Done means the lint is suppressed for the import inside the annotated module, with coverage for the reported case.
