Auto merge of rust-lang#102684 - JhonnyBillM:delete-target-data-layou…

…t-errors-wrapper, r=davidtwco Move `IntoDiagnostic` conformance for `TargetDataLayoutErrors` into `rustc_errors` Addressed this suggestion rust-lang#101558 (comment). This way we comply with the Coherence rule given that `IntoDiagnostic` trait is defined in `rustc_errors`, and almost all other crates depend on it.
