chore: restore windows-sys 0.52 compatibility

windows-sys 0.59 changed `HANDLE` from `isize` to `*mut c_void`. This
only matters in two places that check for null. Doing that check in
terms of std's `RawHandle` before converting to the windows-sys type
makes the code compatible with either version.
