Rollup merge of #55785 - stjepang:unsized-drop-forget, r=alexcrichton
Add mem::forget_unsized() for forgetting unsized values ~~Allows passing values of `T: ?Sized` types to `mem::drop` and `mem::forget`.~~ Adds `mem::forget_unsized()` that accepts `T: ?Sized`. I had to revert the PR that removed the `forget` intrinsic and replaced it with `ManuallyDrop`: https://github.com/rust-lang/rust/pull/40559 We can't use `ManuallyDrop::new()` here because it needs `T: Sized` and we don't have support for unsized return values yet (will we ever?). r? @eddyb
