Auto merge of #102684 - JhonnyBillM:delete-target-data-layout-errors-wrapper, r=davidtwco

Move `IntoDiagnostic` conformance for `TargetDataLayoutErrors` into `rustc_errors`

Addressed this suggestion #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.
