Convert closures into futures based on greenthread **on bare-metal (no_std + no_alloc)**.

In a word, this is a `#![no_std]` version of [Futurify](https://github.com/robertohuertasm/futurify).

I'm exploring to use it to implement bare-metal threading.

## Example

TODO. 

Now just take a unit test as an example:

```rust

#[tokio::test]

async fn test() {

  let h1 = tokio::spawn(ThreadFuture::from(|| {

    println!("1.1");

    yield_now();

    println!("1.2");

    1u32

  }));

  let h2 = tokio::spawn(ThreadFuture::from(|| {

    println!("2.1");

    yield_now();

    println!("2.2");

    2u32

  }));

  println!("join 1 => {}", h1.await.unwrap());

  println!("join 2 => {}", h2.await.unwrap());

}

```

Output:

```

1.1

2.1

1.2

2.2

join 1 => 1

join 2 => 2

```
