Uplift `clippy::undropped_manually_drops` lint

This PR aims at uplifting the `clippy::undropped_manually_drops` lint.

## `undropped_manually_drops`

(warn-by-default)

The `undropped_manually_drops` lint check for calls to `std::mem::drop` with a value of `std::mem::ManuallyDrop` which doesn't drop.

### Example

```rust
struct S;
drop(std::mem::ManuallyDrop::new(S));
```

### Explanation

`ManuallyDrop` does not drop it's inner value so calling `std::mem::drop` will not drop the inner value of the `ManuallyDrop` either.
