Use `HandleOrNull` and `HandleOrInvalid` in the Windows FFI bindings.
Use the new `HandleOrNull` and `HandleOrInvalid` types that were introduced as part of [I/O safety] in a few functions in the Windows FFI bindings. This factors out an `unsafe` block and two `unsafe` function calls in the Windows implementation code. And, it helps test `HandleOrNull` and `HandleOrInvalid`, which indeed turned up a bug: `OwnedHandle` also needs to be `#[repr(transparent)]`, as it's used inside of `HandleOrNull` and `HandleOrInvalid` which are also `#[repr(transparent)]`. [I/O safety]: https://github.com/rust-lang/rust/issues/87074
