Add implementations of AsFd for &T and &mut T, so that users can
write code like this:
pub fn fchown<F: AsFd>(fd: F, uid: Option<u32>, gid: Option<u32>) -> io::Result<()> {with fd: F rather than fd: &F.
And similar for AsHandle and AsSocket on Windows.
Also, adjust the fchown example to pass the file by reference. The
code can work either way now, but passing by reference is more likely
to be what users will want to do.
This is an alternative to #93869, and is a simpler way to achieve the
same goals: users don't need to pass borrowed-BorrowedFd arguments,
and it prevents a pitfall in the case where users write fd: F instead
of fd: &F.
