Tracking issue: #145036

This includes an incredibly low-effort search to find uses that could be switched to using these methods. I only searched for cast::<\w> and cast::<MaybeUninit because there would otherwise be way too much to look through, and I also didn't modify anything inside submodules/subtrees.

As mentioned in the tracking issue, since MaybeUninit only supports Sized types, we need a separate block because <T: PointeeSized> is still too lax for MaybeUninit.
