Suggest enclosing format string with `""` under special cases
This commit adds suggestions on enclosing format string with `""` when it falls into the following 3 cases: `{}`, `{:?}`, `{:#?}` as mentioned in rust-lang/rust#155508.
Currently, this commit only recognizes the above 3 cases. I wonder if we should generalize this to more cases, for example, appying this suggestion to `Block`s with only 0 or 1 `Stmt`, such as `{:#x}`, `{:^10}`, `{abc}`.
