For E0277 suggest adding `Result` return type for function when using QuestionMark `?` in the body.

Adding suggestions for following function in E0277.

```rust
fn main() {
    let mut _file = File::create("foo.txt")?;
}
```

to

```rust
fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut _file = File::create("foo.txt")?;

    return Ok(());
}
```

According to the issue rust-lang#125997, only the code examples in the issue are targeted, but the issue covers a wider range of situations.

According to:
rust-lang#128084 (comment)
https://github.com/rust-lang/rust/pull/126187/files#r1634897691

I try to add a span field to `Block` which doesn't include brace '{' and '}', because I need to add a suggestion at the end of function's body, and this can help me find the right place. But this will make `Block` larger.

I don't want to break the original span field in `Block`, I'm worried that it will cause a lot of code failures and I think it may be more intuitive for span to include braces.
