Timer facilities for Rust's async story

Minimal Rust version: async/await

## Timed

```rust
#![feature(async_await)]

async fn job() {
}

async fn do_job() {
    let work = unsafe {
        async_timer::Timed::platform_new_unchecked(job(), core::time::Duration::from_secs(1))
    };

    match work.wait().await {
        Ok(_) => println!("I'm done!"),
        //You can `Expired::retry` to resume it
        Err(expired) => println!("Job expired: {}", expired),
    }
}
```

## Interval

```rust
#![feature(async_await)]

async fn job() {
}

async fn do_a_while() {
    let mut times: u8 = 0;
    let mut interval = async_timer::Interval::platform_new(core::time::Duration::from_secs(1));

    while times < 5 {
        job().await;
        interval = interval.next().await;
        times += 1;
    }
}
```
