Rollup merge of #96673 - oli-obk:tait_impl_diagnostic, r=petrochenkov
Report that opaque types are not allowed in impls even in the presence of other errors

fixes  #96569

before this PR those useful errors were hidden because either `unused parameter` or `only traits defined in the current crate can be implemented for arbitrary types` got emitted first.
