`undocumented_unsafe_blocks` false positive on `const`s

Summary

See repro, as it's self-explanatory.

Lint Name

undocumented_unsafe_blocks

Reproducer

#![deny(clippy::undocumented_unsafe_blocks)]

// Safety: foo
const _: () = unsafe {};

The lint fires, but it should not, as a safety comment is present on the preceding line. This is the case regardless of configuration.

always wonder how this lint was able to check comments 🤔 , so I'm gonna try @rustbot claim

as it turns out, there was a similar issue (#10832) which got fixed by adding a configuration to this lint.

adding accept-comment-above-statement = true should fix this

As I said in the original issue, this occurs regardless of configuration.
