Rollup merge of rust-lang#145113 - petrochenkov:lessfinalize, r=lcnr

resolve: Do not finalize shadowed bindings

I.e. do not mark them as used, or non-speculatively loaded, or similar.
Previously they were sometimes finalized during early resolution, causing issues like rust-lang#144793 (comment).
