Test formatting of chains containing mixed function calls and method calls

[dtolnay]

The use case from rust-lang/rustfmt#3157 (comment). Rustfmt formats as:

fn example() {
    let some_very_very_long_name = |x, y| x + y;
    let x = "1"
        .parse::<i32>()
        .unwrap()
        .as_method(some_very_very_long_name)(2)
    .count_ones();

    println! {"{x}"};
}

Looks like prettyplease handles this "correctly". Current output:

fn example() {
    let some_very_very_long_name = |x, y| x + y;
    let x = "1"
        .parse::<i32>()
        .unwrap()
        .as_method(some_very_very_long_name)(2)
        .count_ones();
    println!("{x}");
}
