Rollup merge of #101875 - fmease:allow-more-negative-copy-impls, r=lcnr 
Allow more `!Copy` impls

You can already implement `!Copy` for a lot of types (with `#![feature(negative_impls)]`). However, before this PR you could not implement `!Copy` for ADTs whose fields don't implement `Copy` which didn't make any sense. Further, you couldn't implement `!Copy` for types impl'ing `Drop` (equally nonsensical).

Fixes #101836.
