Auto merge of #86190 - asquared31415:extern-main-86110-fix, r=varkor
Fix ICE when `main` is declared in an `extern` block Changes in #84401 to implement `imported_main` changed how the crate entry point is found, and a declared `main` in an `extern` block was detected erroneously. This was causing the ICE described in #86110. This PR adds a check for this case and emits an error instead. Previously a `main` declaration in an `extern` block was not detected as an entry point at all, so emitting an error shouldn't break anything that worked previously. In 1.52.1 stable this is demonstrated, with a `` `main` function not found`` error. Fixes #86110
