Rollup merge of #144050 - JonathanBrouwer:cross-crate-reexport, r=jdonszelmann

Fix encoding of link_section and no_mangle cross crate

Fixes rust-lang/rust#144004

``@bjorn3`` suggested using the `codegen_fn_attrs` query but given that these attributes are not that common it's probably fine to just always encode them. I can also go for that solution if it is preferred but that would require more changes.

r? ``@jdonszelmann`` ``@fmease`` (whoever feels like it)
