Rollup merge of #60691 - topecongiro:await-macro-span, r=Centril

Include expression to wait for to the span of Await

Currently the span of `await!` only includes itself:

```rust
    await!(3);
//  ^^^^^
```

This PR changes it so that the span holds the whole `await!` expression:

```rust
    await!(3);
//  ^^^^^^^^^
