- Do not set the fd as a property on the native object.
- Use the already-existent `GetFD()` method to pass the
fd from C++ to JS.
- Cache the fd in JS to avoid repeated accesses to the
C++ getter.
- Set the fd to `-1` after close, thus reliably making
subsequent calls using the `FileHandle` return `EBADF`.
