Unrolled build for rust-lang#132577

Rollup merge of rust-lang#132577 - Urgau:check-cfg-report-extern-macro, r=petrochenkov

Report the `unexpected_cfgs` lint in external macros

This PR marks the `unexpected_cfgs` lint as being reportable in external macros, as it's probably not the intention of the macro author to leave ineffective cfgs in the users code.

Fixes rust-lang#132572
