Rollup merge of #133374 - RalfJung:abi_unsupported_vector_types, r=jieyouxu

show abi_unsupported_vector_types lint in future breakage reports

The lint is now riding the train to 1.84. Given that crater found no case of this lint triggering at all, IMO it's fine to make it "report in deps" already for 1.85.
