Auto merge of #146328 - zetanumbers:fix-141951, r=lcnr
Skip typeck for items w/o their own typeck context Skip items which forward typeck to their ancestor. Should remove some potential but unnecessary typeck query waits, hence might improve performance for the parallel frontend. Thanks to `@ywxt` for a fix suggestion Fixes rust-lang/rust#141951
