Rollup merge of #139753 - folkertdev:naked-function-unsafe-attribute, r=tgross35,traviscross

Make `#[naked]` an unsafe attribute

tracking issue: rust-lang/rust#138997

Per rust-lang/rust#134213 (comment), the `#[naked]` attribute is now an unsafe attribute (in any edition).

This can only be merged when the above PRs are merged, I'd just like to see if there are any CI surprises here, and maybe there is early review feedback too.

r? ``@traviscross``
