This adds a new type called `DeferredFdCloser` that can be used to close
files by their fd in a way that is safe even if the file is currently

This is done by grabbing an extra refcount to the file and dropping it
in a task work once we return to userspace.
See comments on `binder_do_fd_close` and commit `80cd795630d65` for
motivation.
Please provide links, at least for the doc comment.
