Rollup merge of #91437 - dtolnay:emptybrace, r=nagisa 
Pretty print empty blocks as {}

**Example:**

```rust
macro_rules! p {
    ($e:expr) => {
        println!("{}", stringify!($e));
    };
    ($i:item) => {
        println!("{}", stringify!($i));
    };
}

fn main() {
    p!(if true {});
    p!(struct S {});
}
```

**Before:**

```console
if true { }
struct S {
}
```

**After:**

```console
if true {}
struct S {}
```

This affects [`dbg!`](https://doc.rust-lang.org/std/macro.dbg.html), as well as ecosystem uses of stringify such as in [`anyhow::ensure!`](https://docs.rs/anyhow/1/anyhow/macro.ensure.html). Printing a `{ }` in today's heavily rustfmt'd world comes out looking jarring/sloppy.
