Document that ManuallyDrop::drop should not called more than once
Double dropping is unsound (e.g. https://github.com/rust-lang/rust/issues/60977). This commit documents the fact that `ManuallyDrop::drop` should not be called multiple times on the same instance, as it might not be immediately obvious that this counts as a use of uninitialized data.
