refactor: make Process#kill() throw sensible errors on Windows (#9111)
Previously, calling `Process#kill()` after the process had exited would sometimes throw a `TypeError` on Windows. After this patch, it will throw `NotFound` instead, just like other platforms. This patch also fixes flakiness of the `runKillAfterStatus` test on Windows.
