Unrolled build for rust-lang#139353

Rollup merge of rust-lang#139353 - nnethercote:LateAnon, r=compiler-errors

Fix `Debug` impl for `LateParamRegionKind`.

It uses `Br` prefixes which are inappropriate and appear to have been incorrectly copy/pasted from the `Debug` impl for `BoundRegionKind`.

r? `@BoxyUwU`
