Instead of mapping FDs to `FileHandle`, map them to a `FileDescriptor` trait object. The goal is to eventually have both `FileHandle` as well as `Stdin`, `Stdout` and `Stderr` implement this trait so that syscalls involving FDs can handle both `File`s as well as the standard IO streams.

Remove unreachable intrinsic

This is now supported by the interpreter with https://github.com/rust-lang/rust/pull/74459. We can remove this intrinsic implementation here.
This is covered by this test: https://github.com/rust-lang/miri/blob/master/tests/compile-fail/unreachable.rs

I guess we need to wait until the rust-lang/rust PR merges into nightly, and then we can update `rust-version` hash in the PR, right?
