Rollup merge of #140519 - compiler-errors:name-based-comparison, r=oli-obk

Use select in projection lookup in `report_projection_error`

Using `for_each_relevant_impl` doesn't actually select the correct impl; we can use `select` here to actually get the correct impl with certainty. Follow-up to rust-lang/rust#140278.
