Make all `manual_*` lints do not delete comments during fix

[MKowalski8]

Problem

As for now, we have some inconsistency when it comes to manual_* lints. Some delete comments while fix and some doesn't. We want to make all of them support saving comments, like below:

From:

fn main() {
  let foo: Option::<i32> = Option::None;
  // This is just a variable.
  let _foo = match foo {
      Option::Some(_) => true,
      Option::None => {
          // do something
          false
      },
  };
}

To:

    fn main() {
        let foo: Option<i32> = Option::None;
        // This is just a variable.
        // do something
        let _foo = foo.is_some();
    }

At the moment // do something will be deleted.

Proposed Solution

manual_unwrap_or_default has universal solution that can be applied to other lints
