bea7113eb8 Add impl FileDescriptor for stdin, stdout, stderr
- Use `FileDescriptor::read` for stdin reads
- Use `FileDescriptor::write` for stdout/err writes
- Handle stdout/err reads in `FileDescriptor::read`

Add FileDescriptor trait to abstract fn's on File's and Stdin,Stdout,Stderr

Related issue: #1486

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.

This PR adds the `FileDescriptor` trait and an `impl` for `FileHandle`. I'll open a separate PR for implementing the trait for the standard IO streams.

3386f12eca Wrap io::Result from FileDescriptor::{read,write,seek} in InterpResult
The outer InterpResult will be used to indicate that a fn is not
implemented for a struct(eg. `write` for Stdin).

The inner io::Result is just the result from the read/write/seek.

Due to changes from upstream, a commit using not_undef was inserted, which had to be updated to use check_init.

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?
